USB compatibility list

This is a list of USB devices that have been tested on the Pandora. If the device you want to know about isn't listed here, don't worry! Just go to the USB reference page, look up the specs of your device, and you may be able to figure out if it's compatible.

Networking

Please see the Mobile broadband page for tips on how to get these working, as well as this tutorial from the GP32X forum.

HSDPA (3G) Modems

Please note that many (if not all) USB 3G modems need modemmanager to be installed for switching from mass storage mode to serial communications mode. When first plugged in, most 3G USB modems claim to be a mass storage device and offer, on its built-in flash, drivers and connectivity software to be installed. Mostly this is only for Windows and Mac, so for the Pandora this is not useful. modemmanager instantly takes care of toggling the mode, so that when you plug in the modem, after a few seconds or maybe half a minute modemmanager has switched the modem to communications mode and NetworkManager is able to use it.

If you are using a Firmware before HF7 (or one of its Alpha/Beta versions) you have to install modemmanager. To do so, connect your Pandora to the Internet, open a terminal and, as a super user, intall it via opkg by entering the commands:

sudo opkg update

sudo opkg install modemmanager

Note: If you are using a firmware more recent than "Zaxxon" Hotfix 6 (starting with HF7) you do not have to follow the steps outlined above since modemmanager comes preinstalled.

Note 2: After plugging in the USB 3G modem, it may take some time until NetworkManager is able to use the modem. Wait for at least half a minute, until you give up and report that the modem doesn't work.

Huawei E156G	Not required	Standard-A	USB 2.0	Unknown	Standard-A port	Yes [3]
Huawei E160	Not required	Standard-A	USB 2.0	250mA	Standard-A port	Yes	As the entry for Huawei E220 was wrong, this Current draw could also be wrong. This one definitely needs modemmanager. After installing modemmanager, it works flawlessly.
Huawei E160E	Not required	Standard-A	USB 2.0	250mA	Standard-A port	Yes	As the entry for Huawei E220 was wrong, this Current draw could also be wrong.
Huawei E1750	Not required	Standard-A	USB 2.0	Unknown	Standard-A port	Yes [4]
Huawei E220	Not required	Standard-A	USB 1.1	500mA	Standard-A port via High Speed hub	Not on new kernels.	The successful Pandora E220 tests were done by DJWillis on an old kernel (long before Pandora shipped). It seems that they are NOT working any more. Also tested on Linux (was it working?) This entry originally said 250mA, but there is no source and current sources say 500mA.
4G-Systems XS Stick P14	Not required (usbserial module)	standard-A	USB 2.0	Unknown	Standard-A port	Yes [5]	Requires usbmodeswitch program.
iPhone 3GS (Probably also 1G/3G)	ipheth	Standard-A	USB 2.0	500mA	USB A (Standard-A port?)	Should work in Angstrom with some work.	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.
HTC Desire	not required	Standard-A	USB 2.0	500mA	USB A (Standard-A port?)	Yes	Requires internet connection sharing to be enabled from the phone.

USB to Ethernet adapters

To enable USB Ethernet adapters on the Pandora, you may need to left-click the networking icon on the panel in Xfce, and select "Ifupdown (bnep0)".

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 compat-wireless.

As for hofix 6a4 compat-wireless seems to be present in the kernel out of the box, so one can build a USB wireless driver for Pandora following this algorithm

As for hotfix 6 Release Candidate the kernel includes drivers for these Realtek chips: RTL8712/8188/8191/8192SU/8192CU
