            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. Notes

            
            --------


            Driver updated for kernel 2.6.17.11. (Based on a patch for 2.6.11.4.)


            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 0 and you are using an unknown device (one

            
            not listed below), the driver will map the directional pad to axes (X/Y),

            
            if you said N 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.


            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 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. 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 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 0.0.6), the following devices are included:

            
             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


            The driver should work with xbox pads not listed above as well, however

            
            you will need to do something extra for dance pads to work.


            If you have a controller not listed above, see 0.3 - Unknown Controllers


            If you compiled and installed the driver, test the functionality:

            
            > 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 ;)

            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.

	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. Notes
	--------

	Driver updated for kernel 2.6.17.11. (Based on a patch for 2.6.11.4.)

	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 0 and you are using an unknown device (one
	not listed below), the driver will map the directional pad to axes (X/Y),
	if you said N it will map the d-pad to buttons, which is needed for dance
	style games to function correctly. The default is Y.

	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.
