22 | * This driver is based on: | |
23 | * - information from http://euc.jp/periphs/xbox-controller.ja.html | |
24 | * - the iForce driver drivers/char/joystick/iforce.c | |
25 | * - the skeleton-driver drivers/usb/usb-skeleton.c | |
26 | * | |
27 | * Thanks to: | |
28 | * - ITO Takayuki for providing essential xpad information on his website | |
29 | * - Vojtech Pavlik - iforce driver / input subsystem | |
30 | * - Greg Kroah-Hartman - usb-skeleton driver | |
31 | * | |
32 | * TODO: | |
33 | * - fine tune axes | |
34 | * - fix "analog" buttons (reported as digital now) | |
35 | * - get rumble working | |
36 | * | |
37 | * History: | |
38 | * | |
39 | * 2002-06-27 - 0.0.1 : first version, just said "XBOX HID controller" | |
40 | * | |
41 | * 2002-07-02 - 0.0.2 : basic working version | |
42 | * - all axes and 9 of the 10 buttons work (german InterAct device) | |
43 | * - the black button does not work | |
44 | * | |
45 | * 2002-07-14 - 0.0.3 : rework by Vojtech Pavlik | |
46 | * - indentation fixes | |
47 | * - usb + input init sequence fixes | |
48 | * | |
49 | * 2002-07-16 - 0.0.4 : minor changes, merge with Vojtech's v0.0.3 | |
50 | * - verified the lack of HID and report descriptors | |
51 | * - verified that ALL buttons WORK | |
52 | * - fixed d-pad to axes mapping | |
53 | * | |
54 | * 2002-07-17 - 0.0.5 : simplified d-pad handling | |
