| Requires a good bit of dependencies to get working. Tested with Debian from SD, but should work in Angstrom with some work. The ipheth wwan0 device only provides a connection over the 3G modem, even if you're connected to a wifi network. I used the iproxy and SSH tunneling method with proxychains to get to the wifi network.

====USB WiFi adapters====

====USB WiFi adapters====
The Pandora stock kernel doesn't seem to come with any wireless driver support outside of the internal wifi chip. The only way you'll get wireless working is to build your own kernel with it included or try [http://wireless.kernel.org/en/users/Download compat-wireless].

====USB WiFi adapters====
The Pandora stock kernel doesn't seem to come with any wireless driver support outside of the internal wifi chip. The only way you'll get wireless working is to build your own kernel with it included or try [http://wireless.kernel.org/en/users/Download compat-wireless].

===Input device===
----
Any HID ([http://en.wikipedia.org/wiki/Human_interface_device Human Interface Device]) compliant keyboard, mouse or game controller should work on the Pandora. Most of those device are low speed or full speed USB device and will need to be connected though either a USB OTG adapter/cable or a USB2 hub in order to work on the Pandora.

Zapman: /* Known bugs and how to fix them */

|developer=
|porter=Pickle

}}

DOSBox is an emulator for older x86 systems. Latest update: Nov. 9, 2010.

The Pandora can emulate "[http://www.gp32x.com/board/index.php?/topic/53942-post-your-dosbox-successes-here/page__view__findpost__p__875218 about 5000 cycles in DosBox], which is roughly a 386/33Mhz x86 PC.

==Simple way to get DOSBox working==
1. Put your DOS game directories in <code>/media/[your SD card]/pandora/appdata/dosbox/games</code>

2. Open up dboxfe, the DOSBox GUI that comes with the download.

3. Click on the default profile, click "start". (before doing that, you can click on the "systems" tab, and set "cycles" to "max", for better speed)

4. Type in <code>cd [directory where your game is located]</code>. For example, if you want to play Keen 4 and it's in the directory "Keen4", you would type in <code>cd keen4</code>

5. Type in the name of the executable file for your game, with or without the extension (it's usually the one ending in .exe or .bat). So for "keen4.exe", you would type in <code>keen4</code>. (some games will want you to run setup.exe first - in which case, you type in <code>setup</code>)

6. The game should now start. By the way, at any time in steps 4 or 5, you can type in <code>dir /p</code> or just <code>dir</code> to see a list of the files and directories in that folder

7. To quit DOSBox, close your game (in most games, you press the "Esc" key), then type in <code>exit</code>.

==Assigning action keys to A/B/X/Y==
By default, DOSBox on the Pandora just assigns keys to their regular keyboard positions. This makes playing games very awkward unless you remap them to the action buttons.

The simplest way to do this is to go to the <code>/media/[your SD card]/pandora/appdata/dosbox/.dboxfe</code> directory and edit the mapper.txt file that you'll find there (if you can't see it, press CTRL and the "H" key to view hidden files).

To make things really simple, download [http://pandorawiki.org/images/Mapper.txt this mapper.txt file] and copy it into that directory, replacing the existing mapper.txt file. Then you'll get the following key mappings when you start a game in Dboxfe:

A (key 278)=lctrl

B (key 279)=rshift

Y (key 280)=space

X (key 281)=lalt

L (key 303)=rshift

R (key 305)=lalt

That should be comfortable, since most DOS games use Space, Alt, Ctrl or Shift for their action buttons. Enter is also used (usually to bring up a menu), but it's already in a comfortable spot on the Pandora.

===Using the keymapper===
You can also re-assign keys by using the keymapper in dboxfe. However, for mysterious reasons, the method doesn't work for some people ([http://www.gp32x.com/board/index.php?/topic/58346-dosbox-problems/page__view__findpost__p__935919]).

1. Open dboxfe, select your profile, press "start".

2. As it says on the blue box at the top, press Ctrl+F1 to activate the keymapper (by the way: R is also Ctrl on the Pandora)

3. A screen will pop up. Use the touchscreen to select keys. The bottom part of the screen is below the taskbar on the Pandora, so you'll need to press Shift+leftclick to move the window around. The easiest way is to hold the left shoulder button (which is "Shift", by default) while moving the window with the stylus.

4. "Ctrl", "Alt", "Shift" and "Space" are used as the action keys by most DOS games. By default, A/B/X/Y are mapped to home/end/pg up/pg down.[http://www.gp32x.com/board/index.php?/topic/58346-dosbox-problems/page__view__findpost__p__935632] Remove the mappings for those keys (select them in the keymapper window, and press "del" for each in turn), and then map "Ctrl", "Alt", "Shift" and "Space" to A/B/X/Y.

==Mounting ISOs (CD games)==
Read [http://www.gp32x.com/board/index.php?/topic/54011-dosbox-guide/page__view__findpost__p__882686 this].

==Known bugs and how to fix them==
*In order to use the colon symbol, [http://www.gp32x.com/board/index.php?/topic/53973-dosbox-cant-use-colon/page__pid__933150__st__0&#entry933150 you have to press shift (left shoulder button) + Fn + ";"]. This also goes for the underscore symbol.
*For mysterious reasons, dboxfe will sometimes open up in Z: instead of in C:, as it should. If that happens, go to <code>/media/[your SD card]/pandora/appdata/dosbox/</code>, and delete the configuration files for DOSBox and DOSBoxFE (if you can't see any, press CTRL and the "H" key to view hidden files). Running it again after that should show that everything is back to normal. -[http://boards.openpandora.org/index.php?/topic/2063-dosbox/page__view__findpost__p__41700]
*In '''Jazz Jackrabbit CD''', the character will always walk to the left. Prometheus [http://boards.openpandora.org/index.php?/topic/2063-dosbox/page__view__findpost__p__42081 says]: ''"Whilst I do not know what causes it, I now know that trying to load Jazz from a folder that was set up on another machine (in this case, my main computer, which runs Xubuntu) seems to result in the problem with Jazz automatically walking to the left. Just now, I re-copied the files afresh (which I described on the other forum, previously), and, here's the important bit: I ran the setup program on the Pandora. This seems to have solved the issue for me, although I don't know exactly why that would be."''
*Note that activating the checkbox of "dboxFE -> System -> Render -> aspect" will enable the correct aspect ratio (4:3) for most games but it will also render your nub input and touch screen unusable [http://www.gp32x.com/board/index.php?/topic/56659-dosbox-problems-with-nub-input/page__view__findpost__p__941226]. Fix still needed.

==Other tips==
*Replace DOS4GW with DOS/32A extender (Not working for some games...for example, later Sierra Games like Larry 7 or Gabriel Knight 2). Every little bit helps. -[http://www.gp32x.com/board/index.php?/topic/53942-post-your-dosbox-successes-here/page__view__findpost__p__891743]

*An important thing to try when game doesn't work or is unstable is to run it with the normal core setting rather than dynamic. -[http://www.gp32x.com/board/index.php?/topic/53942-post-your-dosbox-successes-here/page__view__findpost__p__892011]

Zapman: /* OTG host mode */

==Readme First!==

If you have a question to ask, that isn't covered in this FAQ already, please ask over on the [http://www.gp32x.com/board/index.php?showforum=61 Forums].

==USB FAQ==

===How many USB ports does Pandora have?===
Pandora has two USB ports:
* 1x USB 2.0 host port (USB standard-A receptacle)
* 1x USB 1.1/2.0 OTG port (USB mini-AB receptacle)

===What does “host port” mean?===
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 (only if they are '''high speed compliant'''!), and provide up to 500mA (the maximum allowed according to USB standards).

===What does “OTG” mean?===
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).

===What’s all this stuff about USB 1.1 and USB 2.0? Isn’t USB, uh, universal?===
USB 1.1 is a subset of the USB 2.0 protocol. Among many other things, the USB 2.0 standard introduced high-speed data transmission, which requires a special controller on the host side. Most USB ports (eg. on your computer’s motherboard, in USB hubs) actually contain '''two chips''' to allow universal compatibility – one that takes care of the Low-Speed (1.0 Mbit/s) and Full-Speed (12 Mbit/s) devices, and another one for the Hi-Speed (480 Mbit/s) devices. The reason is that Low-Speed and Full-Speed are essentially the same protocols operated at different clock frequencies. Hi-Speed is a completely new development and nothing like the other two.

For reasons beyond our control, Pandora’s USB standard-A host port does not contain this second chip. Only USB 2.0 devices bearing the “USB HI-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 HI-SPEED” logo.

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.

===So which devices are which?===
[[Image:USB-HighSpeed-certified-Logo.png|thumb|alt=USB High Speed Certified logo|Devices bearing this logo are certified High Speed devices. They can be plugged directly into Pandora's USB 2.0 host port.]]
There are no set rules. As a very general guide:
* Common Low-Speed and Full-Speed devices include keyboards, mice, headsets, older USB devices.
* Common Hi-Speed devices include cameras, PMPs, HDDs, hubs, card readers, thumb drives.
This is just a rough representation of what’s out there in the wild, and you will find exceptions. Devices like HSDPA modems and GPS units could fall into either category. The only reliable indication of true Hi-Speed compatibility is the “USB Hi-Speed Certified” logo (right).

===Arrgh, USB used to be simple. What can I actually connect to Pandora?===
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.

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]].

The various USB connection scenarios are as follows:

==Pandora as USB slave==
[[Image:Pandora.usb.slave.png|thumb|alt=Pandora as USB slave|Pandora as USB slave]]
Using a USB standard-A to mini-B cable (the kind you probably own several of), you can:
* Transfer data to/from Pandora
* Charge Pandora's battery.

'''Note:'''
* Charging Pandora from your computer's USB port is best done with Pandora in standby mode. The current provided by your computer will probably not be sufficient to provide a quick charge while Pandora is being used.
* There are USB standard-A to mini-B cables that can be used to charge your Pandora but don't work to transfer data to/ from the Pandora! MSWindows will complain abount "An unknown device connected". Try using a different cable.

==Hosting USB devices==
[[Image:Pandora.usb.host.png|thumb|alt=Pandora as a USB host|Pandora as a USB host]]
*Directly plug in a Hi-Speed USB 2.0 device such as a thumb drive, or a Huawei E160 modem.
*Using a USB standard-A to USB standard-B (or mini-B, micro-B, depending on what's on the device) cable, connect Hi-Speed USB 2.0 devices such as cameras, PMPs, and HDDS.
*Connect a USB hub, which will enable you to to connect other non-Hi-Speed USB devices such as keyboards, mice, or a Huawei E220 modem.

'''Note:'''
*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.

==OTG host mode==
[[Image:Pandora.usb.otg.host.png|thumb|alt=Pandora in OTG host mode|Pandora in OTG host mode]]
How you connect a device to the mini-AB OTG port depends on the device's USB connector.
*standard-B receptacle: Use a mini-A to standard-B cable.
*mini-B receptacle: Use a mini-A to mini-B cable.
*micro-B receptacle: Use a mini-A plug to standard-A receptacle adapter and a standard-A to micro-B cable.
*standard-A plug: Use a mini-A plug to standard-A receptacle adapter.
*mini-A plug: No extra cable or adapter needed.
*micro-A plug: No standardized solution exists.

This port allows you to connect any USB 2.0-compliant device (Hi-Speed, Full-Speed, Low-Speed, including USB 1.1 ones) directly, without the use of a hub.

'''Notes:'''
*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.
*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.
*If you have trouble connecting any device to the smal OTG port, check if 'Setting->Startup->Enable/Disable services on boot->Start USB Network on bootup' is checked! This needs to be set in order to work. Default setting is unchecked (Better naming of this option is planned for Hotfix5, see [http://www.gp32x.com/board/index.php?/topic/56516-wishlist-for-hf5/]).

'''Host mode connector'''
[[Image:Mini-usb.png|thumb|alt=mini-B and Mini-A comparison|mini-B and Mini-A comparison]]
Shown here are a Mini-B connector (left, black) and a Mini-A connector (right, white). The mini-a connector should be the one you want in order to use the OTG port in host mode. Click on the image for a larger version.

With the right connector, it is not necessary to switch the mode of the port[http://www.gp32x.com/board/index.php?/topic/55396-how-do-you-put-the-usb-otg-port-into-host-mode/], it will be done automatically. It may also be possible to force a mode switch, but this has not been clarified by the devs, and could result in two devices both attempting to power the port (which is not recommended)

(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).

===What’s all this stuff about USB 1.1 and USB 2.0? Isn’t USB, uh, universal?===
USB 1.1 is a subset of the USB 2.0 protocol. Among many other things, the USB 2.0 standard introduced high-speed data transmission, which requires a special controller on the host side. Most USB ports (eg. on your computer’s motherboard, in USB hubs) actually contain '''two chips''' to allow universal compatibility – one that takes care of the Low-Speed (1.0 Mbit/s) and Full-Speed (12 Mbit/s) devices, and another one for the Hi-Speed (480 Mbit/s) devices. The reason is that Low-Speed and Full-Speed are essentially the same protocols operated at different clock frequencies. Hi-Speed is a completely new development and nothing like the other two.

For reasons beyond our control, Pandora’s USB standard-A host port does not contain this second chip. Only USB 2.0 devices bearing the “USB HI-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 HI-SPEED” logo.

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.

===So which devices are which?===
[[Image:USB-HighSpeed-certified-Logo.png|thumb|alt=USB High Speed Certified logo|Devices bearing this logo are certified High Speed devices. They can be plugged directly into Pandora's USB 2.0 host port.]]
There are no set rules. As a very general guide:
* Common Low-Speed and Full-Speed devices include keyboards, mice, headsets, older USB devices.
* Common Hi-Speed devices include cameras, PMPs, HDDs, hubs, card readers, thumb drives.
This is just a rough representation of what’s out there in the wild, and you will find exceptions. Devices like HSDPA modems and GPS units could fall into either category. The only reliable indication of true Hi-Speed compatibility is the “USB Hi-Speed Certified” logo (right).

===Arrgh, USB used to be simple. What can I actually connect to Pandora?===
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.

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]].

The various USB connection scenarios are as follows:

==Pandora as USB slave==
[[Image:Pandora.usb.slave.png|thumb|alt=Pandora as USB slave|Pandora as USB slave]]
Using a USB standard-A to mini-B cable (the kind you probably own several of), you can:
* Transfer data to/from Pandora
* Charge Pandora's battery.

'''Note:'''
* Charging Pandora from your computer's USB port is best done with Pandora in standby mode. The current provided by your computer will probably not be sufficient to provide a quick charge while Pandora is being used.
* There are USB standard-A to mini-B cables that can be used to charge your Pandora but don't work to transfer data to/ from the Pandora! MSWindows will complain abount "An unknown device connected". Try using a different cable.

==Hosting USB devices==
[[Image:Pandora.usb.host.png|thumb|alt=Pandora as a USB host|Pandora as a USB host]]
*Directly plug in a Hi-Speed USB 2.0 device such as a thumb drive, or a Huawei E160 modem.
*Using a USB standard-A to USB standard-B (or mini-B, micro-B, depending on what's on the device) cable, connect Hi-Speed USB 2.0 devices such as cameras, PMPs, and HDDS.
*Connect a USB hub, which will enable you to to connect other non-Hi-Speed USB devices such as keyboards, mice, or a Huawei E220 modem.

'''Note:'''
*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.

==OTG host mode==
[[Image:Pandora.usb.otg.host.png|thumb|alt=Pandora in OTG host mode|Pandora in OTG host mode]]
How you connect a device to the mini-AB OTG port depends on the device's USB connector.
*standard-B receptacle: Use a mini-A to standard-B cable.
*mini-B receptacle: Use a mini-A to mini-B cable.
*micro-B receptacle: Use a mini-A plug to standard-A receptacle adapter and a standard-A to micro-B cable.
*standard-A plug: Use a mini-A plug to standard-A receptacle adapter.
*mini-A plug: No extra cable or adapter needed.
*micro-A plug: No standardized solution exists.

This port allows you to connect any USB 2.0-compliant device (Hi-Speed, Full-Speed, Low-Speed, including USB 1.1 ones) directly, without the use of a hub.

'''Notes:'''
*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.
*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.
*If you have trouble connecting any device to the smal OTG port, check if 'Setting->Startup->Enable/Disable services on boot->Start USB Network on bootup' is checked! This needs to be set in order to work (Better naming of this option in planned for Hotfix5, see [http://www.gp32x.com/board/index.php?/topic/56516-wishlist-for-hf5/]).

'''Host mode connector'''
[[Image:Mini-usb.png|thumb|alt=mini-B and Mini-A comparison|mini-B and Mini-A comparison]]
Shown here are a Mini-B connector (left, black) and a Mini-A connector (right, white). The mini-a connector should be the one you want in order to use the OTG port in host mode. Click on the image for a larger version.

With the right connector, it is not necessary to switch the mode of the port[http://www.gp32x.com/board/index.php?/topic/55396-how-do-you-put-the-usb-otg-port-into-host-mode/], it will be done automatically. It may also be possible to force a mode switch, but this has not been clarified by the devs, and could result in two devices both attempting to power the port (which is not recommended)

==USB FAQ==

===How many USB ports does Pandora have?===
Pandora has two USB ports:
* 1x USB 2.0 host port (USB standard-A receptacle)
* 1x USB 1.1/2.0 OTG port (USB mini-AB receptacle)

===What does “host port” mean?===
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 (only if they are '''high speed compliant'''!), and provide up to 500mA (the maximum allowed according to USB standards).

===What does “OTG” mean?===
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.

===How many USB ports does Pandora have?===
Pandora has two USB ports:
* 1x USB 2.0 host port (USB standard-A receptacle)
* 1x USB 1.1/2.0 OTG port (USB mini-AB receptacle)

===What does “host port” mean?===
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).

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).

===What’s all this stuff about USB 1.1 and USB 2.0? Isn’t USB, uh, universal?===
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.

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.

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.

===So which devices are USB 1.1, and which ones are USB 2.0?===
[[Image:USB-HighSpeed-certified-Logo.png|thumb|alt=USB High Speed Certified logo|Devices bearing this logo are certified High Speed devices. They can be plugged directly into Pandora's USB 2.0 host port.]]
There are no set rules. As a very general guide:
* Common USB 1.1 devices include keyboards, mice, headsets, older USB devices.
* Common USB 2.0 devices include cameras, PMPs, HDDs, hubs, card readers, thumb drives.
This is just a rough representation of what’s out there in the wild, and you will find exceptions. 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 Certified” logo (right).

===Arrgh, USB used to be simple. What can I actually connect to Pandora?===
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.

How you connect a device to the mini-AB OTG port depends on the device's USB connector.
*standard-B receptacle: Use a mini-A to standard-B cable.
*mini-B receptacle: Use a mini-A to mini-B cable.
*micro-B receptacle: Use a mini-A plug to standard-A receptacle adapter and a standard-A to micro-B cable.
*standard-A plug: Use a mini-A plug to standard-A receptacle adapter.
*mini-A plug: No extra cable or adapter needed.
*micro-A plug: No standardized solution exists.

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.

'''Notes:'''
*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.
*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.

'''Host mode connector'''

Shown here are a Mini-B connector (left, black) and a Mini-A connector (right, white). The mini-a connector should be the one you want in order to use the OTG port in host mode. Click on the image for a larger version.

With the right connector, it is not necessary to switch the mode of the port[http://www.gp32x.com/board/index.php?/topic/55396-how-do-you-put-the-usb-otg-port-into-host-mode/], it will be done automatically. It may also be possible to force a mode switch, but this has not been clarified by the devs, and could result in two devices both attempting to power the port (which is not recommended)
