34 | * Thanks to: | |
35 | * - ITO Takayuki for providing essential xpad information on his website | |
36 | * - Vojtech Pavlik - iforce driver / input subsystem | |
37 | * - Greg Kroah-Hartman - usb-skeleton driver | |
d518b2b4 | 38 | * - XBOX Linux project - extra USB id's |
1da177e4 LT |
39 | * |
40 | * TODO: | |
deb8ee43 | 41 | * - fine tune axes (especially trigger axes) |
1da177e4 LT |
42 | * - fix "analog" buttons (reported as digital now) |
43 | * - get rumble working | |
deb8ee43 | 44 | * - need USB IDs for other dance pads |
1da177e4 LT |
45 | * |
46 | * History: | |
47 | * | |
48 | * 2002-06-27 - 0.0.1 : first version, just said "XBOX HID controller" | |
49 | * | |
50 | * 2002-07-02 - 0.0.2 : basic working version | |
51 | * - all axes and 9 of the 10 buttons work (german InterAct device) | |
52 | * - the black button does not work | |
53 | * | |
54 | * 2002-07-14 - 0.0.3 : rework by Vojtech Pavlik | |
55 | * - indentation fixes | |
56 | * - usb + input init sequence fixes | |
57 | * | |
58 | * 2002-07-16 - 0.0.4 : minor changes, merge with Vojtech's v0.0.3 | |
59 | * - verified the lack of HID and report descriptors | |
60 | * - verified that ALL buttons WORK | |
61 | * - fixed d-pad to axes mapping | |
62 | * | |
63 | * 2002-07-17 - 0.0.5 : simplified d-pad handling | |
d518b2b4 DC |
64 | * |
65 | * 2004-10-02 - 0.0.6 : DDR pad support | |
66 | * - borrowed from the XBOX linux kernel | |
67 | * - USB id's for commonly used dance pads are present | |
68 | * - dance pads will map D-PAD to buttons, not axes | |
69 | * - pass the module paramater 'dpad_to_buttons' to force | |
70 | * the D-PAD to map to buttons if your pad is not detected | |
