usb-xpad - Linux USB driver for XBOX HID gamecontrollers
xpad - Linux USB driver for X-Box gamepads
This is the very first release of a driver for XBOX gamecontrollers.
This is the very first release of a driver for X-Box gamepads.
Basically, this was hacked away in just a few hours, so don't expect
miracles.
In particular, there is currently NO support for the rumble pack.
You won't find many ff-aware linux applications anyway.

8 axes and 10 buttons.
Alls 8 axes work, though they all have the same range (-32768..32767)
and the zero-setting is not correct for the triggers.
9 of the 10 buttons work (my black button does not work, though I can
see no reason for it not to), all of them are in digital mode, though
(the six buttons on the right side are "analog" ones).
and the zero-setting is not correct for the triggers (I don't know if that
is some limitation of jstest, since the input device setup should be fine. I
didn't have a look at jstest itself yet).
All of the 10 buttons work (in digital mode). The six buttons on the
right side (A, B, X, Y, black, white) are said to be "analog" and
report their values as 8 bit unsigned, not sure what this is good for.
I tested the controller with quake3, and configuration and
in game functionality were OK. However, I find it rather difficult to
play first person shooters with a pad. Your mileage may vary.

Before you can actually use the driver, you need to get yourself an
adapter cable to connect the XBOX-controller to your Linux-Box.

Once you have the adapter cable and the controller is connected, you need
to load your USB subsystem and should cat /proc/bus/usb/devices.
There should be an entry like the one in InterAct_german.dump.
There should be an entry like the one at the end [4].
Currently (as of version 0.0.4), the following three devices are included:
original Microsoft XBOX controller (US), vendor=0x045e, product=0x0202
original Microsoft XBOX controller (Japan), vendor=0x045e, product=0x0285
InterAct PowerPad Pro (Germany), vendor=0x05fd, product=0x107a
Don't worry if the vendor and/or product ID don't match, those are easy to
add to the driver. You could do it yourself, just add the appropriate line
into the list after the line
'} xpad_device[] = {'
, but before the line that says
'{ 0x0000, 0x0000, "unknown...." }'.
If you have another controller that is not listed above and is not recognized
by the driver, please drop me a line with the appropriate info (that is, include
the name, vendor and product ID, as well as the country where you bought it;
sending the whole dump out of /proc/bus/usb/devices along would be even better).
In theory, the driver should work with other controllers than mine
(InterAct PowerPad pro, bought in Germany) just fine, but see for yourself.
(InterAct PowerPad pro, bought in Germany) just fine, but I cannot test this
for I only have this one controller.
If you compiled and installed the driver, test the functionality:
> modprobe usb-xpad
> modprobe xpad
> modprobe joydev
> jstest /dev/input/js0
> jstest /dev/js0
There should be a single line showing 18 inputs (8 axes, 10 buttons), and
it's values should change if you move the sticks and push the buttons.
