The last time this documentation was accurate was just over 8 years ago. In this time we've added support for two new generations of Xbox console controllers and dozens of third-party controllers. This patch unifies terminology and makes it explicit which model of controller a sentence refers to. It also expands certain sections to address the latest versions of Xbox controllers. Thus this documentation should now be useful to end users and not contain out-right untruths. This is the patch's second revision. Prior versions of this patch altered the driver's TODO list. That change has been pulled out of this documentation update patch. Signed-off-by: Daniel Dressler <danieru.dressler@gmail.com> Signed-off-by: Jonathan Corbet <corbet@lwn.net>

xpad - Linux USB driver for Xbox compatible controllers
|
|
|
|
This driver exposes all first-party and third-party Xbox compatible
|
|
controllers. It has a long history and has enjoyed considerable usage
|
|
as Window's xinput library caused most PC games to focus on Xbox
|
|
controller compatibility.
|
|
|
|
Due to backwards compatibility all buttons are reported as digital.
|
|
This only effects Original Xbox controllers. All later controller models
|
|
have only digital face buttons.
|
|
|
|
Rumble is supported on some models of Xbox 360 controllers but not of
|
|
Original Xbox controllers nor on Xbox One controllers. As of writing
|
|
the Xbox One's rumble protocol has not been reverse engineered but in
|
|
the future could be supported.
|
|
|
|
|
|
0. Notes
|
|
--------
|
|
The number of buttons/axes reported varies based on 3 things:
|
|
- if you are using a known controller
|
|
- if you are using a known dance pad
|
|
- if using an unknown device (one not listed below), what you set in the
|
|
module configuration for "Map D-PAD to buttons rather than axes for unknown
|
|
pads" (module option dpad_to_buttons)
|
|
|
|
If you set dpad_to_buttons to N and you are using an unknown device
|
|
the driver will map the directional pad to axes (X/Y).
|
|
If you said Y it will map the d-pad to buttons, which is needed for dance
|
|
style games to function correctly. The default is Y.
|
|
|
|
dpad_to_buttons has no effect for known pads. A erroneous commit message
|
|
claimed dpad_to_buttons could be used to force behavior on known devices.
|
|
This is not true. Both dpad_to_buttons and triggers_to_buttons only affect
|
|
unknown controllers.
|
|
|
|
|
|
0.1 Normal Controllers
|
|
----------------------
|
|
With a normal controller, the directional pad is mapped to its own X/Y axes.
|
|
The jstest-program from joystick-1.2.15 (jstest-version 2.1.0) will report 8
|
|
axes and 10 buttons.
|
|
|
|
All 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.
|
|
|
|
|
|
0.2 Xbox Dance Pads
|
|
-------------------
|
|
When using a known dance pad, jstest will report 6 axes and 14 buttons.
|
|
|
|
For dance style pads (like the redoctane pad) several changes
|
|
have been made. The old driver would map the d-pad to axes, resulting
|
|
in the driver being unable to report when the user was pressing both
|
|
left+right or up+down, making DDR style games unplayable.
|
|
|
|
Known dance pads automatically map the d-pad to buttons and will work
|
|
correctly out of the box.
|
|
|
|
If your dance pad is recognized by the driver but is using axes instead
|
|
of buttons, see section 0.3 - Unknown Controllers
|
|
|
|
I've tested this with Stepmania, and it works quite well.
|
|
|
|
|
|
0.3 Unknown Controllers
|
|
----------------------
|
|
If you have an unknown xbox controller, it should work just fine with
|
|
the default settings.
|
|
|
|
HOWEVER if you have an unknown dance pad not listed below, it will not
|
|
work UNLESS you set "dpad_to_buttons" to 1 in the module configuration.
|
|
|
|
PLEASE, if you have an unknown controller, email Dom <binary1230@yahoo.com> with
|
|
a dump from /proc/bus/usb and a description of the pad (manufacturer, country,
|
|
whether it is a dance pad or normal controller) so that we can add your pad
|
|
to the list of supported devices, ensuring that it will work out of the
|
|
box in the future.

1. USB adapters
|
|
--------------
|
|
All generations of Xbox controllers speak USB over the wire.
|
|
- Original Xbox controllers use a proprietary connector and require adapters.
|
|
- Wireless Xbox 360 controllers require a 'Xbox 360 Wireless Gaming Receiver
|
|
for Windows'
|
|
- Wired Xbox 360 controllers use standard USB connectors.
|
|
- Xbox One controllers can be wireless but speak Wi-Fi Direct and are not
|
|
yet supported.
|
|
- Xbox One controllers can be wired and use standard Micro-USB connectors.
|
|
|
|
|
|
|
|
1.1 Original Xbox USB adapters
|
|
--------------
|
|
Using this driver with an Original Xbox controller requires an
|
|
adapter cable to break out the proprietary connector's pins to USB.
|
|
You can buy these online fairly cheap, or build your own.
|
|
|
|
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 1.0 connectors).
|
|
|
|
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, if needed, and the controller connected
|
|
the xpad module should be auto loaded. To confirm you can cat
|
|
/proc/bus/usb/devices. There should be an entry like the one at the end [4].
|
|
|
|
|
|
|
|
3. Supported Controllers
|
|
------------------------
|
|
For a full list of supported controllers and associated vendor and product
|
|
IDs see the xpad_device[] array[6].
|
|
|
|
As of the historic version 0.0.6 (2006-10-10) the following devices
|
|
were supported:
|
|
original Microsoft XBOX controller (US), vendor=0x045e, product=0x0202
|
|
smaller Microsoft XBOX controller (US), vendor=0x045e, product=0x0289
|
|
original Microsoft XBOX controller (Japan), vendor=0x045e, product=0x0285
|
|
InterAct PowerPad Pro (Germany), vendor=0x05fd, product=0x107a
|
|
RedOctane Xbox Dance Pad (US), vendor=0x0c12, product=0x8809
|
|
|
|
Unrecognized models of Xbox controllers should function as Generic
|
|
Xbox controllers. Unrecognized Dance Pad controllers require setting
|
|
the module option 'dpad_to_buttons'.
|
|
|
|
If you have an unrecognized controller please see 0.3 - Unknown Controllers
|
|
|
|
|
|
4. Manual Testing
|
|
-----------------
|
|
To test this driver's functionality you may use 'jstest'.
|
|
|
|
For example:
|
|
> modprobe xpad
|
|
> modprobe joydev
|
|
> jstest /dev/js0
|
|
|
|
If you're using a normal controller, there should be a single line showing
|
|
18 inputs (8 axes, 10 buttons), and its values should change if you move
|
|
the sticks and push the buttons. If you're using a dance pad, it should
|
|
show 20 inputs (6 axes, 14 buttons).
|
|
|
|
It works? Voila, you're done ;)
|
|

5. 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.
