1======================================================= 2xpad - Linux USB driver for Xbox compatible controllers 3======================================================= 4 5This driver exposes all first-party and third-party Xbox compatible 6controllers. It has a long history and has enjoyed considerable usage 7as Window's xinput library caused most PC games to focus on Xbox 8controller compatibility. 9 10Due to backwards compatibility all buttons are reported as digital. 11This only effects Original Xbox controllers. All later controller models 12have only digital face buttons. 13 14Rumble is supported on some models of Xbox 360 controllers but not of 15Original Xbox controllers nor on Xbox One controllers. As of writing 16the Xbox One's rumble protocol has not been reverse engineered but in 17the future could be supported. 18 19 20Notes 21===== 22 23The number of buttons/axes reported varies based on 3 things: 24 25- if you are using a known controller 26- if you are using a known dance pad 27- if using an unknown device (one not listed below), what you set in the 28 module configuration for "Map D-PAD to buttons rather than axes for unknown 29 pads" (module option dpad_to_buttons) 30 31If you set dpad_to_buttons to N and you are using an unknown device 32the driver will map the directional pad to axes (X/Y). 33If you said Y it will map the d-pad to buttons, which is needed for dance 34style games to function correctly. The default is Y. 35 36dpad_to_buttons has no effect for known pads. A erroneous commit message 37claimed dpad_to_buttons could be used to force behavior on known devices. 38This is not true. Both dpad_to_buttons and triggers_to_buttons only affect 39unknown controllers. 40 41 42Normal Controllers 43------------------ 44 45With a normal controller, the directional pad is mapped to its own X/Y axes. 46The jstest-program from joystick-1.2.15 (jstest-version 2.1.0) will report 8 47axes and 10 buttons. 48 49All 8 axes work, though they all have the same range (-32768..32767) 50and the zero-setting is not correct for the triggers (I don't know if that 51is some limitation of jstest, since the input device setup should be fine. I 52didn't have a look at jstest itself yet). 53 54All of the 10 buttons work (in digital mode). The six buttons on the 55right side (A, B, X, Y, black, white) are said to be "analog" and 56report their values as 8 bit unsigned, not sure what this is good for. 57 58I tested the controller with quake3, and configuration and 59in game functionality were OK. However, I find it rather difficult to 60play first person shooters with a pad. Your mileage may vary. 61 62 63Xbox Dance Pads 64--------------- 65 66When using a known dance pad, jstest will report 6 axes and 14 buttons. 67 68For dance style pads (like the redoctane pad) several changes 69have been made. The old driver would map the d-pad to axes, resulting 70in the driver being unable to report when the user was pressing both 71left+right or up+down, making DDR style games unplayable. 72 73Known dance pads automatically map the d-pad to buttons and will work 74correctly out of the box. 75 76If your dance pad is recognized by the driver but is using axes instead 77of buttons, see section 0.3 - Unknown Controllers 78 79I've tested this with Stepmania, and it works quite well. 80 81 82Unknown Controllers 83------------------- 84 85If you have an unknown xbox controller, it should work just fine with 86the default settings. 87 88HOWEVER if you have an unknown dance pad not listed below, it will not 89work UNLESS you set "dpad_to_buttons" to 1 in the module configuration. 90 91 92USB adapters 93============ 94 95All generations of Xbox controllers speak USB over the wire. 96 97- Original Xbox controllers use a proprietary connector and require adapters. 98- Wireless Xbox 360 controllers require a 'Xbox 360 Wireless Gaming Receiver 99 for Windows' 100- Wired Xbox 360 controllers use standard USB connectors. 101- Xbox One controllers can be wireless but speak Wi-Fi Direct and are not 102 yet supported. 103- Xbox One controllers can be wired and use standard Micro-USB connectors. 104 105 106 107Original Xbox USB adapters 108-------------------------- 109 110Using this driver with an Original Xbox controller requires an 111adapter cable to break out the proprietary connector's pins to USB. 112You can buy these online fairly cheap, or build your own. 113 114Such a cable is pretty easy to build. The Controller itself is a USB 115compound device (a hub with three ports for two expansion slots and 116the controller device) with the only difference in a nonstandard connector 117(5 pins vs. 4 on standard USB 1.0 connectors). 118 119You just need to solder a USB connector onto the cable and keep the 120yellow wire unconnected. The other pins have the same order on both 121connectors so there is no magic to it. Detailed info on these matters 122can be found on the net ([1]_, [2]_, [3]_). 123 124Thanks to the trip splitter found on the cable you don't even need to cut the 125original one. You can buy an extension cable and cut that instead. That way, 126you can still use the controller with your X-Box, if you have one ;) 127 128 129 130Driver Installation 131=================== 132 133Once you have the adapter cable, if needed, and the controller connected 134the xpad module should be auto loaded. To confirm you can cat 135/sys/kernel/debug/usb/devices. There should be an entry like those: 136 137.. code-block:: none 138 :caption: dump from InterAct PowerPad Pro (Germany) 139 140 T: Bus=01 Lev=03 Prnt=04 Port=00 Cnt=01 Dev#= 5 Spd=12 MxCh= 0 141 D: Ver= 1.10 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=32 #Cfgs= 1 142 P: Vendor=05fd ProdID=107a Rev= 1.00 143 C:* #Ifs= 1 Cfg#= 1 Atr=80 MxPwr=100mA 144 I: If#= 0 Alt= 0 #EPs= 2 Cls=58(unk. ) Sub=42 Prot=00 Driver=(none) 145 E: Ad=81(I) Atr=03(Int.)

Unrecognized Dance Pad controllers require setting 178the module option 'dpad_to_buttons'. 179 180If you have an unrecognized controller please see 0.3 - Unknown Controllers 181 182 183Manual Testing 184============== 185 186To test this driver's functionality you may use 'jstest'. 187 188For example:: 189 190 > modprobe xpad 191 > modprobe joydev 192 > jstest /dev/js0 193 194If you're using a normal controller, there should be a single line showing 19518 inputs (8 axes, 10 buttons), and its values should change if you move 196the sticks and push the buttons. If you're using a dance pad, it should 197show 20 inputs (6 axes, 14 buttons). 198 199It works? Voila, you're done ;) 200 201 202 203Thanks 204====== 205 206I have to thank ITO Takayuki for the detailed info on his site 207 http://euc.jp/periphs/xbox-controller.ja.html. 208 209His useful info and both the usb-skeleton as well as the iforce input driver 210(Greg Kroah-Hartmann; Vojtech Pavlik) helped a lot in rapid prototyping 211the basic functionality. 212 213 214 215References 216========== 217 218..
