Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

xpad - Linux USB driver for X-Box gamepads
|
|
|
|
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.
|
|
|
|
|
|
0. Status
|
|
---------
|
|
|
|
For now, this driver has only been tested on just one Linux-Box.
|
|
This one is running a 2.4.18 kernel with usb-uhci on an amd athlon 600.
|
|
|
|
The jstest-program from joystick-1.2.15 (jstest-version 2.1.0) reports
|
|
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 (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.
|
|
|
|
|
|
1. USB adapter
|
|
--------------
|
|
|
|
Before you can actually use the driver, you need to get yourself an
|
|
adapter cable to connect the X-Box controller to your Linux-Box.
|
|
|
|
Such a cable is pretty easy to build. The Controller itself is a USB compound
|
|
device (a hub with three ports for two expansion slots and the controller
|
|
device) with the only difference in a nonstandard connector (5 pins vs. 4 on
|
|
standard USB connector).
|
|
|
|
You just need to solder a USB connector onto the cable and keep the
|
|
yellow wire unconnected. The other pins have the same order on both
|
|
connectors so there is no magic to it. Detailed info on these matters
|
|
can be found on the net ([1], [2], [3]).
|
|
|
|
Thanks to the trip splitter found on the cable you don't even need to cut the
|
|
original one. You can buy an extension cable and cut that instead. That way,
|
|
you can still use the controller with your X-Box, if you have one ;)
|
|
|
|
|
|
2. driver installation
|
|
----------------------
|
|
|
|
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 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
|
|
|
|
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 I cannot test this
|
|
for I only have this one controller.
|
|
|
|
If you compiled and installed the driver, test the functionality:
|
|
> modprobe xpad
|
|
> modprobe joydev
|
|
> 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.
|
|
|
|
It works? Voila, your done ;)
|
|
|
|
|
|
3. Thanks

I have to thank ITO Takayuki for the detailed info on his site
|
|
http://euc.jp/periphs/xbox-controller.ja.html.
|
|
|
|
His useful info and both the usb-skeleton as well as the iforce input driver
|
|
(Greg Kroah-Hartmann; Vojtech Pavlik) helped a lot in rapid prototyping
|
|
the basic functionality.
