<div>I think the games should be split into ports and original games. Of course, this might sometimes be hard to decide, for example with Wizzley Presto, which is a new original game but could also be called a port from the iPhone version... [[User:OrR|OrR]]<br />
<br />
I think that's a good idea. But I got stuck on that same blurred line while planning a blog feature for homebrew games. Wizzley Presto is one, also GP2X games like Pool Panic and Battle Jewels. For my purposes (being to showcase our scene's own work) I decided that these games should fall under originals, because (i) it's all talent from within our scene, and (ii) the original authors are doing the porting. I don't know if we can apply such subjective rules to wiki categories though. [[User:Gruso|Gruso]]<br />
<br />
How about 3 categories:<br />
*ports of classic games<br />
*ports from other platforms<br />
*original Pandora games<br />

<br />
==USB FAQ==<br />
<br />
===How many USB ports does Pandora have?===<br />
Pandora has two USB ports:<br />
* 1x USB 2.0 host port (USB standard-A receptacle)<br />
* 1x USB 1.1/2.0 OTG port (USB mini-AB receptacle)<br />
<br />
===What does “host port” mean?===<br />
A USB host port “hosts” any device that you plug in, just like the USB ports on your computer. Pandora’s full size USB A port can host USB 2.0 devices, and provide up to 500mA (the maximum allowed according to USB standards).<br />
<br />
===What does “OTG” mean?===<br />
OTG stands for On The Go. USB OTG ports can operate in two different modes. When connected through this port, the Pandora can act as a device, for example when connected to a computer for charging & data transfer. For this mode, you need a standard-A to mini-B cable. However, the Pandora can also act as a host port for USB 1.1 and USB 2.0 devices. For details on how to make the necessary cable connection, see [[USB_reference#OTG_host_mode|the OTG host mode section]]. This port can supply a maximum of 100mA in host mode. Although this port implements On The Go functionality, it can not get an official On The Go certification because the OTG specification requires a device to have exactly one USB port. (The Pandora has two.) Also, the mini-AB connector used on the Pandora has been taken out of the specification in 2007 (but is still widely adopted).<br />
<br />
===What’s all this stuff about USB 1.1 and USB 2.0? Isn’t USB, uh, universal?===<br />
The USB 2.0 protocol is not backwards compatible with USB 1.1. Most USB ports (eg. on your computer’s motherboard, in USB hubs) actually contain two chips to allow universal compatibility – one for USB 1.1, and one for USB 2.0.<br />
<br />
Pandora’s USB standard-A host port does not contain this second chip. Only USB 2.0 devices bearing the “USB HIGH SPEED” logo can be plugged directly into this port. However, USB 1.1 devices can be connected to this port through a USB hub, provided the hub bears the “USB HIGH SPEED” logo.<br />
<br />
Pandora’s USB OTG (mini-AB) port is fully compatible with both USB 1.1 and USB 2.0, allowing it to host either type of device.<br />
<br />
===So which devices are USB 1.1, and which ones are USB 2.0?===<br />
There are no rules, and with so many manufacturers making so many different devices, it's impossible to give a definitive answer. As a general guide though:<br />
* Common USB 1.1 devices: Keyboards, mice, webcams, headsets, older USB devices.<br />
* Common USB 2.0 devices: Cameras, PMPs, HDDs, hubs, card readers, thumb drives.<br />
Just to reiterate, this is a very general guide. It’s not based on any rules, it’s just a rough representation of what’s out there in the wild. Devices like HSDPA modems and GPS units could fall into either category. The only reliable indication of true USB 2.0 compatibility is the “USB HIGH SPEED” logo.<br />
<br />
===Arrgh, USB used to be simple. What can I actually connect to Pandora?===<br />
Almost anything, as long as it's supported by Linux. Think of a USB device that everybody uses (mouse, keyboard, thumb drive...) and chances are it will be a simple matter of plug and play. But this might not be the case for more specialised USB devices (modems, ethernet adapters, USB displays...), many of which will only function with Windows specific drivers.<br />
<br />
If you intend to purchase USB accessories for use with Pandora, you should first research Linux support for that type of device. Devices already tested on Pandora will be added to the [[USB compatibility list]].<br />
<br />
The various USB connection scenarios are as follows:<br />
<br />
==Pandora as USB slave==<br />
[[Image:Pandora.usb.slave.png|thumb|alt=Pandora as USB slave|Pandora as USB slave]]<br />
Using a USB standard-A to mini-B cable (the kind you probably own several of), you can:<br />
* Transfer data to/from Pandora<br />
* Charge Pandora's battery.<br />
<br />
'''Note:'''<br />
*Charging Pandora from your computer's USB port is best done with Pandora in standby mode, or switched off. The current provided by your computer will probably not be sufficient to provide an effective charge while Pandora is being used.<br />
<br />
==Hosting USB devices==<br />
[[Image:Pandora.usb.host.png|thumb|alt=Pandora as a USB host|Pandora as a USB host]]<br />
*Directly plug in a USB 2.0 device such as a thumb drive, or a Huawei E160 modem.<br />
*Using a USB standard-A to USB standard-B (or mini-B, micro-B, depending on what's on the device) cable, connect USB 2.0 devices such as cameras, PMPs, and HDDS.<br />
*Connect a USB hub, which will enable you to to connect USB 1.1 devices such as keyboards, mice, or a Huawei E220 modem.<br />
<br />
'''Note:'''<br />
*This port can supply a maximum of 500mA. If you plan to use a USB HDD, note that very few of these can draw sufficient power from a single USB port. A powered HDD caddy or powered USB hub will be necessary in most cases.<br />
<br />
==OTG host mode==<br />
[[Image:Pandora.usb.otg.host.png|thumb|alt=Pandora in OTG host mode|Pandora in OTG host mode]]<br />
How you connect a device to the mini-AB OTG port depends on the device's USB connector.<br />
*standard-B receptacle: Use a mini-A to standard-B cable.<br />
*mini-B receptacle: Use a mini-A to mini-B cable.<br />
*micro-B receptacle: Use a mini-A plug to standard-A receptacle adapter and a standard-A to micro-B cable.<br />
*standard-A plug: Use a mini-A plug to standard-A receptacle adapter.<br />
*mini-A plug: No extra cable or adapter needed.<br />
*micro-A plug: No standardized solution exists.<br />
<br />
This port allows you to connect a USB 1.1 device directly, without the use of a hub. This port is also USB 2.0 compliant.<br />
<br />
'''Notes:'''<br />
*mini-A and mini-AB connectors have been removed from the present USB standard. This means that the above connectors may vanish from the market at some point (although there will probably be demand for them for some time). There are a lot of connectors available that were never standardized. It is recommended that you do not use them as they may lead to non-working connections. Stick to the cables and adapters mentioned above and look for a mention of "OTG" or "On The Go" and you should be on the safe side.<br />
*In host mode, this port can supply a maximum of 100mA. USB 1.1 devices that draw more than 100mA will need to connect to Pandora's other USB port via a hub, as depicted in the previous example. The Huawei E220 is one such device.<br />

How you connect a device to the mini-AB OTG port depends on the device's USB connector.<br />
*standard-B receptacle: Use a mini-A to standard-B cable.<br />
*mini-B receptacle: Use a mini-A to mini-B cable.<br />
*micro-B receptacle: Use a mini-A plug to standard-A receptacle adapter and a standard-A to micro-B cable.<br />
*standard-A plug: Use a mini-A plug to standard-A receptacle adapter.<br />
*mini-A plug: No extra cable or adapter needed.<br />
<br />
This port allows you to connect a USB 1.1 device directly, without the use of a hub. This port is also USB 2.0 compliant.<br />
<br />
'''Notes:'''<br />
*mini-A and mini-AB connectors have been removed from the present USB standard. This means that the above connectors may vanish from the market at some point (although there will probably be demand for them for some time). There are a lot of connectors available that were never standardized. It is recommended that you do not use them as they may lead to non-working connections. Stick to the cables and adapters mentioned above and look for a mention of "OTG" or "On The Go" and you should be on the safe side.<br />
*In host mode, this port can supply a maximum of 100mA. USB 1.1 devices that draw more than 100mA will need to connect to Pandora's other USB port via a hub, as depicted in the previous example. The Huawei E220 is one such device.<br />

==USB FAQ==<br />
<br />
===How many USB ports does Pandora have?===<br />
Pandora has two USB ports:<br />
* 1x USB 2.0 host port (USB standard-A receptacle)<br />
* 1x USB 1.1/2.0 OTG port (USB mini-AB receptacle)<br />
<br />
===What does “host port” mean?===<br />
A USB host port “hosts” any device that you plug in, just like the USB ports on your computer. Pandora’s full size USB A port can host USB 2.0 devices, and provide up to 500mA (the maximum allowed according to USB standards).<br />
<br />
===What does “OTG” mean?===<br />
OTG stands for On The Go. USB OTG ports can operate in two different modes. When connected through this port, the Pandora can act as a device, for example when connected to a computer for charging & data transfer. For this mode, you need a standard-A to mini-B cable. However, the Pandora can also act as a host port for USB 1.1 and USB 2.0 devices. For details on how to make the necessary cable connection, see [[USB_reference#OTG_host_mode|the OTG host mode section]]. This port can supply a maximum of 100mA in host mode. Although this port implements On The Go functionality, it can not get an official On The Go certification because the OTG specification requires a device to have exactly one USB port. (The Pandora has two.) Also, the mini-AB connector used on the Pandora has been taken out of the specification in 2007 (but is still widely adopted).<br />
<br />
===What’s all this stuff about USB 1.1 and USB 2.0? Isn’t USB, uh, universal?===<br />
The USB 2.0 protocol is not backwards compatible with USB 1.1. Most USB ports (eg. on your computer’s motherboard, in USB hubs) actually contain two chips to allow universal compatibility – one for USB 1.1, and one for USB 2.0.<br />
<br />
Pandora’s USB standard-A host port does not contain this second chip. Only USB 2.0 devices bearing the “USB HIGH SPEED” logo can be plugged directly into this port. However, USB 1.1 devices can be connected to this port through a USB hub, provided the hub bears the “USB HIGH SPEED” logo.<br />
<br />
Pandora’s USB OTG (mini-AB) port is fully compatible with both USB 1.1 and USB 2.0, allowing it to host either type of device.<br />
<br />
===So which devices are USB 1.1, and which ones are USB 2.0?===<br />
There are no rules, and with so many manufacturers making so many different devices, it's impossible to give a definitive answer. As a general guide though:<br />
* Common USB 1.1 devices: Keyboards, mice, webcams, headsets, older USB devices.<br />
* Common USB 2.0 devices: Cameras, PMPs, HDDs, hubs, card readers, thumb drives.<br />
Just to reiterate, this is a very general guide. It’s not based on any rules, it’s just a rough representation of what’s out there in the wild. Devices like HSDPA modems and GPS units could fall into either category. The only reliable indication of true USB 2.0 compatibility is the “USB HIGH SPEED” logo.<br />
<br />
===Arrgh, USB used to be simple. What can I actually connect to Pandora?===<br />
Almost anything, as long as it's supported by Linux. Think of a USB device that everybody uses (mouse, keyboard, thumb drive...) and chances are it will be a simple matter of plug and play. But this might not be the case for more specialised USB devices (modems, ethernet adapters, USB displays...), many of which will only function with Windows specific drivers.<br />
<br />
If you intend to purchase USB accessories for use with Pandora, you should first research Linux support for that type of device. Devices already tested on Pandora will be added to the [[USB compatibility list]].<br />
<br />
The various USB connection scenarios are as follows:<br />
<br />
==Pandora as USB slave==<br />
[[Image:Pandora.usb.slave.png|thumb|alt=Pandora as USB slave|Pandora as USB slave]]<br />
Using a USB standard-A to mini-B cable (the kind you probably own several of), you can:<br />
* Transfer data to/from Pandora<br />
* Charge Pandora's battery.<br />
<br />
'''Note:'''<br />
*Charging Pandora from your computer's USB port is best done with Pandora in standby mode, or switched off. The current provided by your computer will probably not be sufficient to provide an effective charge while Pandora is being used.<br />
<br />
==Hosting USB devices==<br />
[[Image:Pandora.usb.host.png|thumb|alt=Pandora as a USB host|Pandora as a USB host]]<br />
*Directly plug in a USB 2.0 device such as a thumb drive, or a Huawei E160 modem.<br />
*Using a USB standard-A to USB standard-B (or mini-B, micro-B, depending on what's on the device) cable, connect USB 2.0 devices such as cameras, PMPs, and HDDS.<br />
*Connect a USB hub, which will enable you to to connect USB 1.1 devices such as keyboards, mice, or a Huawei E220 modem.<br />
<br />
'''Note:'''<br />
*This port can supply a maximum of 500mA. If you plan to use a USB HDD, note that very few of these can draw sufficient power from a single USB port. A powered HDD caddy or powered USB hub will be necessary in most cases.<br />
<br />
==OTG host mode==<br />
[[Image:Pandora.usb.otg.host.png|thumb|alt=Pandora in OTG host mode|Pandora in OTG host mode]]<br />
How you connect a device to this port depends on the device's USB connector.<br />

*A purpose built OTG adapter must be used. Various non-standard USB cables and adapters (such as gender changers) can be used to turn a mini-AB port into a standard-A port, but this will often not work. OTG adapters can be found on Amazon and eBay.<br />

<hr />
<div>The Pandora is a seventh-generation handheld game console. When it ships, it will be the most powerful handheld gaming console available.<br />
[[Image:Pandora-newrender.jpg|Right|thumb|360px|The Pandora open-source game system.]]<br />
<br />
==Overview==<br />
<br />
The Pandora will run a Linux distribution. There will be no fees for developer tools and hence anyone will be free to develop and release games for the system. <br />
<br />
===Core===<br />
<br />
The Pandora uses a Texas Instruments OMAP 3530 System-on-Chip. This includes the ARM Cortex-A8 processor, the TI C64X programmable DSP, the PowerVR SGX 530 3D accelerator and supporting components.<br />
<br />
====Storage====<br />
The first revisions of the console included 128MB of DDR RAM, and 256MB of on-board NAND flash memory. However, the final revision that is sold to consumers has 256MB of DDR RAM and 512MB of on-board NAND memory. Storage space is available through 2 SDHC card slots and via USB host capabilities for connecting any standard USB flash drive and hard drive.<br />
<br />
===Input and output===<br />
The Pandora includes two analog pads, a directional pad, 4 action buttons, 2 shoulder buttons, 3 function buttons (start/select/home), and a QWERTY keyboard. <br />
<br />
====Display====<br />
The Pandora's display will be a 800*480 display, which additionally will have touchscreen functionality.<br />
<br />
=====TV-out=====<br />
The Pandora will have the ability to output S-video and composite signals to television sets. In addition, picture-in-picture and seperate signals for the TV and LCD will be supported.<br />
<br />
====Sound====<br />
The Pandora will have a high-quality sound DAC, and an ADC and internal microphone for recording. A pair of stereo speakers is built into the display. The volume control is a wheel.<br />
<br />
====Keyboard====<br />
The Pandora will have an almost-full QWERTY keyboard, with additional keys using Function. Control will likely be mapped onto one of the action or shoulder buttons.<br />

<br />
==USB FAQ==<br />
<br />
===How many USB ports does Pandora have?===<br />
Pandora has two USB ports:<br />
* 1x USB 2.0 host port (USB standard-A receptacle)<br />
* 1x USB 1.1/2.0 OTG port (USB mini-AB receptacle)<br />
<br />
===What does “host port” mean?===<br />
A USB host port “hosts” any device that you plug in, just like the USB ports on your computer. Pandora’s full size USB A port can host USB 2.0 devices, and provide up to 500mA (the maximum allowed according to USB standards).<br />
<br />
===What does “OTG” mean?===<br />
OTG stands for On The Go. USB OTG ports can operate in two different modes. When connected through this port, the Pandora can act as a device, for example when connected to a computer for charging & data transfer. For this mode, you need a standard-A to mini-B cable. However, the Pandora can also act as a host port for USB 1.1 and USB 2.0 devices. For this mode, a mini-A plug to standard-A receptacle adapter as well as a standard-A to standard-B (or mini-B, micro-B, depending on what device you want to connect) cable is needed. This port can supply a maximum of 100mA in host mode. Although this port implements On The Go functionality, it can not get an official On The Go certification because the OTG specification requires a device to have exactly one USB port. (The Pandora has two.) Also, the mini-AB connector used on the Pandora has been taken out of the specification in 2007 (but is still widely adopted).<br />
<br />
===What’s all this stuff about USB 1.1 and USB 2.0? Isn’t USB, uh, universal?===<br />
The USB 2.0 protocol is not backwards compatible with USB 1.1. Most USB ports (eg. on your computer’s motherboard, in USB hubs) actually contain two chips to allow universal compatibility – one for USB 1.1, and one for USB 2.0.<br />
<br />
Pandora’s USB standard-A host port does not contain this second chip. Only USB 2.0 devices bearing the “USB HIGH SPEED” logo can be plugged directly into this port. However, USB 1.1 devices can be connected to this port through a USB hub, provided the hub bears the “USB HIGH SPEED” logo.<br />
<br />
Pandora’s USB OTG (mini-AB) port is fully compatible with both USB 1.1 and USB 2.0, allowing it to host either type of device.<br />
<br />
===So which devices are USB 1.1, and which ones are USB 2.0?===<br />
There are no rules, and with so many manufacturers making so many different devices, it's impossible to give a definitive answer. As a general guide though:<br />
* Common USB 1.1 devices: Keyboards, mice, webcams, headsets, older USB devices.<br />
* Common USB 2.0 devices: Cameras, PMPs, HDDs, hubs, card readers, thumb drives.<br />
Just to reiterate, this is a very general guide. It’s not based on any rules, it’s just a rough representation of what’s out there in the wild. Devices like HSDPA modems and GPS units could fall into either category. The only reliable indication of true USB 2.0 compatibility is the “USB HIGH SPEED” logo.<br />
<br />
===Arrgh, USB used to be simple. What can I actually connect to Pandora?===<br />
Almost anything, as long as it's supported by Linux. Think of a USB device that everybody uses (mouse, keyboard, thumb drive...) and chances are it will be a simple matter of plug and play. But this might not be the case for more specialised USB devices (modems, ethernet adapters, USB displays...), many of which will only function with Windows specific drivers.<br />
<br />
If you intend to purchase USB accessories for use with Pandora, you should first research Linux support for that type of device. Devices already tested on Pandora will be added to the [[USB compatibility list]].<br />
<br />
The various USB connection scenarios are as follows:<br />
<br />
==Pandora as USB slave==<br />
[[Image:Pandora.usb.slave.png|thumb|alt=Pandora as USB slave|Pandora as USB slave]]<br />
Using a USB standard-A to mini-B cable (the kind you probably own several of), you can:<br />
* Transfer data to/from Pandora<br />
* Charge Pandora's battery.<br />
<br />
'''Note:'''<br />
*Charging Pandora from your computer's USB port is best done with Pandora in standby mode, or switched off. The current provided by your computer will probably not be sufficient to provide an effective charge while Pandora is being used.<br />
<br />
==Hosting USB devices==<br />
[[Image:Pandora.usb.host.png|thumb|alt=Pandora as a USB host|Pandora as a USB host]]<br />
*Directly plug in a USB 2.0 device such as a thumb drive, or a Huawei E160 modem.<br />
*Using a USB standard-A to USB standard-B (or mini-B, micro-B, depending on what's on the device) cable, connect USB 2.0 devices such as cameras, PMPs, and HDDS.<br />
*Connect a USB hub, which will enable you to to connect USB 1.1 devices such as keyboards, mice, or a Huawei E220 modem.<br />
<br />
'''Note:'''<br />
*This port can supply a maximum of 500mA. If you plan to use a USB HDD, note that very few of these can draw sufficient power from a single USB port. A powered HDD caddy or powered USB hub will be necessary in most cases.<br />
<br />
==OTG host mode==<br />
[[Image:Pandora.usb.otg.host.png|thumb|alt=Pandora in OTG host mode|Pandora in OTG host mode]]<br />
This function requires a USB mini-A plug to standard-A receptacle adapter (OTG adapter), which will turn the mini-AB port into a full size USB standard-A port. This allows you to connect a USB 1.1 device directly, without the use of a hub. This port is also USB 2.0 compliant.<br />
<br />
'''Notes:'''<br />
*In host mode, this port can supply a maximum of 100mA. USB 1.1 devices that draw more than 100mA will need to connect to Pandora's other USB port via a hub, as depicted in the previous example. The Huawei E220 is one such device.<br />
*A purpose built OTG adapter must be used. Various non-standard USB cables and adapters (such as gender changers) can be used to turn a mini-AB port into a standard-A port, but this will often not work. OTG adapters can be found on Amazon and eBay.<br />

===What does “OTG” mean?===<br />
OTG stands for On The Go. USB OTG ports can operate in two different modes. When connected through this port, the Pandora can act as a device, for example when connected to a computer for charging & data transfer. For this mode, you need a standard-A to mini-B cable. However, the Pandora can also act as a host port for USB 1.1 and USB 2.0 devices. For this mode, a mini-A plug to standard-A receptacle adapter as well as a standard-A to standard-B (or mini-B, micro-B, depending on what device you want to connect) cable is needed. This port can supply a maximum of 100mA in host mode. Although this port implements On The Go functionality, it can not get an official On The Go certification because the OTG specification requires a device to have exactly one USB port. (The Pandora has two.)<br />
<br />
===What’s all this stuff about USB 1.1 and USB 2.0? Isn’t USB, uh, universal?===<br />
The USB 2.0 protocol is not backwards compatible with USB 1.1. Most USB ports (eg. on your computer’s motherboard, in USB hubs) actually contain two chips to allow universal compatibility – one for USB 1.1, and one for USB 2.0.<br />
<br />
Pandora’s USB standard-A host port does not contain this second chip. Only USB 2.0 devices bearing the “USB HIGH SPEED” logo can be plugged directly into this port. However, USB 1.1 devices can be connected to this port through a USB hub, provided the hub bears the “USB HIGH SPEED” logo.<br />
<br />
Pandora’s USB OTG (mini-AB) port is fully compatible with both USB 1.1 and USB 2.0, allowing it to host either type of device.<br />
<br />
===So which devices are USB 1.1, and which ones are USB 2.0?===<br />
There are no rules, and with so many manufacturers making so many different devices, it's impossible to give a definitive answer. As a general guide though:<br />
* Common USB 1.1 devices: Keyboards, mice, webcams, headsets, older USB devices.<br />
* Common USB 2.0 devices: Cameras, PMPs, HDDs, hubs, card readers, thumb drives.<br />
Just to reiterate, this is a very general guide. It’s not based on any rules, it’s just a rough representation of what’s out there in the wild. Devices like HSDPA modems and GPS units could fall into either category. The only reliable indication of true USB 2.0 compatibility is the “USB HIGH SPEED” logo.<br />
<br />
===Arrgh, USB used to be simple. What can I actually connect to Pandora?===<br />
Almost anything, as long as it's supported by Linux. Think of a USB device that everybody uses (mouse, keyboard, thumb drive...) and chances are it will be a simple matter of plug and play. But this might not be the case for more specialised USB devices (modems, ethernet adapters, USB displays...), many of which will only function with Windows specific drivers.<br />
<br />
If you intend to purchase USB accessories for use with Pandora, you should first research Linux support for that type of device. Devices already tested on Pandora will be added to the [[USB compatibility list]].<br />
<br />
The various USB connection scenarios are as follows:<br />
<br />
==Pandora as USB slave==<br />
[[Image:Pandora.usb.slave.png|thumb|alt=Pandora as USB slave|Pandora as USB slave]]<br />
Using a USB standard-A to mini-B cable (the kind you probably own several of), you can:<br />
* Transfer data to/from Pandora<br />
* Charge Pandora's battery.<br />
<br />
'''Note:'''<br />
*Charging Pandora from your computer's USB port is best done with Pandora in standby mode, or switched off. The current provided by your computer will probably not be sufficient to provide an effective charge while Pandora is being used.<br />
<br />
==Hosting USB devices==<br />
[[Image:Pandora.usb.host.png|thumb|alt=Pandora as a USB host|Pandora as a USB host]]<br />
*Directly plug in a USB 2.0 device such as a thumb drive, or a Huawei E160 modem.<br />
*Using a USB standard-A to USB standard-B (or mini-B, micro-B, depending on what's on the device) cable, connect USB 2.0 devices such as cameras, PMPs, and HDDS.<br />
*Connect a USB hub, which will enable you to to connect USB 1.1 devices such as keyboards, mice, or a Huawei E220 modem.<br />
<br />
'''Note:'''<br />
*This port can supply a maximum of 500mA. If you plan to use a USB HDD, note that very few of these can draw sufficient power from a single USB port. A powered HDD caddy or powered USB hub will be necessary in most cases.<br />
<br />
==OTG host mode==<br />
[[Image:Pandora.usb.otg.host.png|thumb|alt=Pandora in OTG host mode|Pandora in OTG host mode]]<br />
This function requires a USB mini-A plug to standard-A receptacle adapter (OTG adapter), which will turn the mini-AB port into a full size USB standard-A port. This allows you to connect a USB 1.1 device directly, without the use of a hub. This port is also USB 2.0 compliant.<br />
<br />
'''Notes:'''<br />
*In host mode, this port can supply a maximum of 100mA. USB 1.1 devices that draw more than 100mA will need to connect to Pandora's other USB port via a hub, as depicted in the previous example. The Huawei E220 is one such device.<br />
*A purpose built OTG adapter must be used. Various USB cables and adapters (such as gender changers) can be used to turn a mini-AB port into a standard-A port, but this will often not work. OTG adapters can be found on Amazon and eBay.<br />

Almost anything, as long as it's supported by Linux. Think of a USB device that everybody uses (mouse, keyboard, thumb drive...) and chances are it will be a simple matter of plug and play. But this might not be the case for more specialised USB devices (modems, ethernet adapters, USB displays...), many of which will only function with Windows specific drivers.<br />
<br />
If you intend to purchase USB accessories for use with Pandora, you should first research Linux support for that type of device. Devices already tested on Pandora will be added to the [[USB compatibility list]].<br />
<br />
The various USB connection scenarios are as follows:<br />
<br />
==Pandora as USB slave==<br />
[[Image:Pandora.usb.slave.png|thumb|alt=Pandora as USB slave|Pandora as USB slave]]<br />
Using a standard USB A to USB Mini B cable (the kind you probably own several of), you can:<br />
* Transfer data to/from Pandora<br />
* Charge Pandora's battery.<br />
<br />
'''Note:'''<br />
*Charging Pandora from your computer's USB port is best done with Pandora in standby mode, or switched off. The current provided by your computer will probably not be sufficient to provide an effective charge while Pandora is being used.<br />
<br />
==Hosting USB devices==<br />
[[Image:Pandora.usb.host.png|thumb|alt=Pandora as a USB host|Pandora as a USB host]]<br />
*Directly plug in a USB 2.0 device such as a thumb drive, or a Huawei E160 modem.<br />
*Using a USB standard-A to USB standard-B (or mini-B, micro-B, depending on what's on the device) cable, connect USB 2.0 devices such as cameras, PMPs, and HDDS.<br />
*Connect a USB hub, which will enable you to to connect USB 1.1 devices such as keyboards, mice, or a Huawei E220 modem.<br />
<br />
'''Note:'''<br />
*This port can supply a maximum of 500mA. If you plan to use a USB HDD, note that very few of these can draw sufficient power from a single USB port. A powered HDD caddy or powered USB hub will be necessary in most cases.<br />
<br />
==OTG host mode==<br />
[[Image:Pandora.usb.otg.host.png|thumb|alt=Pandora in OTG host mode|Pandora in OTG host mode]]<br />
This function requires a USB OTG adapter, which will turn the Mini AB port into a full size USB A port. This allows you to connect a USB 1.1 device directly, without the use of a hub. This port is also USB 2.0 compliant.<br />
<br />
'''Notes:'''<br />
*In host mode, this port can supply a maximum of 100mA. USB 1.1 devices that draw more than 100mA will need to connect to Pandora's other USB port via a hub, as depicted in the previous example. The Huawei E220 is one such device.<br />
*A purpose built OTG adapter must be used. Various USB cables and adapters (such as gender changers) can be used to turn a Mini AB port into a standard A port, but this will not work. OTG adapters can be found on Amazon and eBay.<br />

==USB FAQ==<br />
<br />
===How many USB ports does Pandora have?===<br />
Pandora has two USB ports:<br />
* 1x USB 2.0 host port (USB standard-A receptacle)<br />
* 1x USB 1.1/2.0 OTG port (USB mini-AB receptacle)<br />
<br />
===What does “host port” mean?===<br />
A USB host port “hosts” any device that you plug in, just like the USB ports on your computer. Pandora’s full size USB A port can host USB 2.0 devices, and provide up to 500mA (the maximum allowed according to USB standards).<br />
<br />
===What does “OTG” mean?===<br />
OTG stands for On The Go. USB OTG ports can operate in two different modes. When connected through this port, the Pandora can act as a device, for example when connected to a computer for charging & data transfer. For this mode, you need a standard-A to mini-B cable. However, the Pandora can also act as a host port for USB 1.1 and USB 2.0 devices. For this mode, a mini-A plug to standard-A receptacle adapter as well as a standard-A to standard-B (or mini-B, micro-B, depending on what device you want to connect) cable is needed. This port can supply a maximum of 100mA in host mode. Although this port implements On The Go functionality, it can not get an official On The Go certification because the OTG specification requires a device to have exactly one USB port. (The Pandora has two.)<br />
<br />
===What’s all this stuff about USB 1.1 and USB 2.0? Isn’t USB, uh, universal?===<br />
The USB 2.0 protocol is not backwards compatible with USB 1.1. Most USB ports (eg. on your computer’s motherboard, in USB hubs) actually contain two chips to allow universal compatibility – one for USB 1.1, and one for USB 2.0.<br />
<br />
Pandora’s USB A host port does not contain this second chip. Only USB 2.0 devices bearing the “USB HIGH SPEED” logo can be plugged directly into this port. However, USB 1.1 devices can be connected to this port through a USB hub, provided the hub bears the “USB HIGH SPEED” logo.<br />
<br />
Pandora’s USB OTG (Mini AB) port is fully compatible with both USB 1.1 and USB 2.0, allowing it to host either type of device.<br />
<br />
===So which devices are USB 1.1, and which ones are USB 2.0?===<br />
There are no rules, and with so many manufacturers making so many different devices, it's impossible to give a definitive answer. As a general guide though:<br />
* Common USB 1.1 devices: Keyboards, mice, webcams, headsets, older USB devices.<br />
* Common USB 2.0 devices: Cameras, PMPs, HDDs, hubs, card readers, thumb drives.<br />
Just to reiterate, this is a very general guide. It’s not based on any rules, it’s just a rough representation of what’s out there in the wild. Devices like HSDPA modems and GPS units could fall into either category. The only reliable indication of true USB 2.0 compatibility is the “USB HIGH SPEED” logo.<br />

==USB FAQ==<br />
<br />
===How many USB ports does Pandora have?===<br />
Pandora has two USB ports:<br />
* 1x USB 2.0 host port (Standard “USB A” socket)<br />
* 1x USB 1.1/2.0 OTG port (“Mini AB” socket)<br />
<br />
===What does “host port” mean?===<br />
A USB host port “hosts” any device that you plug in, just like the USB ports on your computer. Pandora’s full size USB A port can host USB 2.0 devices, and provide up to 500mA (the maximum allowed according to USB standards).<br />
<br />
===What does “OTG” mean?===<br />
OTG stands for On The Go. USB OTG ports can operate in two different modes. When connected through this port, the Pandora can act as a device, for example when connected to a computer for charging & data transfer. For this mode, you need a standard-A to mini-B cable. However, the Pandora can also act as a host port for USB 1.1 and USB 2.0 devices. For this mode, a mini-A plug to standard-A receptable adapter as well as a standard-A to standard-B (or mini-B, micro-B, depending on what device you want to connect) is needed. This port can supply a maximum of 100mA in host mode. Although this port implements On The Go functionality, it can not get an official On The Go certification because the OTG specification requires a device to have exactly one USB port. (The Pandora has two.)<br />
<br />
===What’s all this stuff about USB 1.1 and USB 2.0? Isn’t USB, uh, universal?===<br />
The USB 2.0 protocol is not backwards compatible with USB 1.1. Most USB ports (eg. on your computer’s motherboard, in USB hubs) actually contain two chips to allow universal compatibility – one for USB 1.1, and one for USB 2.0.<br />
<br />
Pandora’s USB A host port does not contain this second chip. Only USB 2.0 devices bearing the “USB HIGH SPEED” logo can be plugged directly into this port. However, USB 1.1 devices can be connected to this port through a USB hub, provided the hub bears the “USB HIGH SPEED” logo.<br />
<br />
Pandora’s USB OTG (Mini AB) port is fully compatible with both USB 1.1 and USB 2.0, allowing it to host either type of device.<br />
<br />
===So which devices are USB 1.1, and which ones are USB 2.0?===<br />
There are no rules, and with so many manufacturers making so many different devices, it's impossible to give a definitive answer. As a general guide though:<br />
* Common USB 1.1 devices: Keyboards, mice, webcams, headsets, older USB devices.<br />
* Common USB 2.0 devices: Cameras, PMPs, HDDs, hubs, card readers, thumb drives.<br />
Just to reiterate, this is a very general guide. It’s not based on any rules, it’s just a rough representation of what’s out there in the wild. Devices like HSDPA modems and GPS units could fall into either category. The only reliable indication of true USB 2.0 compatibility is the “USB HIGH SPEED” logo.<br />
<br />
===Arrgh, USB used to be simple. What can I actually connect to Pandora?===<br />
Almost anything, as long as it's supported by Linux. Think of a USB device that everybody uses (mouse, keyboard, thumb drive...) and chances are it will be a simple matter of plug and play. But this might not be the case for more specialised USB devices (modems, ethernet adapters, USB displays...), many of which will only function with Windows specific drivers.<br />
<br />
If you intend to purchase USB accessories for use with Pandora, you should first research Linux support for that type of device. Devices already tested on Pandora will be added to the [[USB compatibility list]].<br />
<br />
The various USB connection scenarios are as follows:<br />
<br />
==Pandora as USB slave==<br />
[[Image:Pandora.usb.slave.png|thumb|alt=Pandora as USB slave|Pandora as USB slave]]<br />
Using a standard USB A to USB Mini A cable (the kind you probably own several of), you can:<br />
* Transfer data to/from Pandora<br />
* Charge Pandora's battery.<br />
<br />
'''Note:'''<br />
*Charging Pandora from your computer's USB port is best done with Pandora in standby mode, or switched off. The current provided by your computer will probably not be sufficient to provide an effective charge while Pandora is being used.<br />
<br />
==Hosting USB devices==<br />
[[Image:Pandora.usb.host.png|thumb|alt=Pandora as a USB host|Pandora as a USB host]]<br />
*Directly plug in a USB 2.0 device such as a thumb drive, or a Huawei E160 modem.<br />
*Using a standard USB A to USB Mini A cable, connect USB 2.0 devices such as cameras, PMPs, and HDDS.<br />
*Connect a USB hub, which will enable you to to connect USB 1.1 devices such as keyboards, mice, or a Huawei E220 modem.<br />
<br />
'''Note:'''<br />
*This port can supply a maximum of 500mA. If you plan to use a USB HDD, note that very few of these can draw sufficient power from a single USB port. A powered HDD caddy or powered USB hub will be necessary in most cases.<br />
<br />
==OTG host mode==<br />
[[Image:Pandora.usb.otg.host.png|thumb|alt=Pandora in OTG host mode|Pandora in OTG host mode]]<br />
This function requires a USB OTG adapter, which will turn the Mini AB port into a full size USB A port. This allows you to connect a USB 1.1 device directly, without the use of a hub. This port is also USB 2.0 compliant.<br />
<br />
'''Notes:'''<br />
*In host mode, this port can supply a maximum of 100mA. USB 1.1 devices that draw more than 100mA will need to connect to Pandora's other USB port via a hub, as depicted in the previous example. The Huawei E220 is one such device.<br />
*A purpose built OTG adapter must be used. Various USB cables and adapters (such as gender changers) can be used to turn a Mini AB port into a standard A port, but this will not work. OTG adapters can be found on Amazon and eBay.<br />
