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 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 ;) + + +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. + + +4.
