35 * Thanks to:
36 * - ITO Takayuki for providing essential xpad information on his website
37 * - Vojtech Pavlik - iforce driver / input subsystem
38 * - Greg Kroah-Hartman - usb-skeleton driver
d518b2b4 39 * - XBOX Linux project - extra USB id's

LT		 40 *
41 * TODO:
deb8ee43 42 * - fine tune axes (especially trigger axes)
1da177e4
LT		 43 * - fix "analog" buttons (reported as digital now)
44 * - get rumble working
deb8ee43 45 * - need USB IDs for other dance pads
1da177e4
LT		 46 *
47 * History:
48 *
49 * 2002-06-27 - 0.0.1 : first version, just said "XBOX HID controller"
50 *
51 * 2002-07-02 - 0.0.2 : basic working version
52 * - all axes and 9 of the 10 buttons work (german InterAct device)
53 * - the black button does not work
54 *
55 * 2002-07-14 - 0.0.3 : rework by Vojtech Pavlik
56 * - indentation fixes
57 * - usb + input init sequence fixes
58 *
59 * 2002-07-16 - 0.0.4 : minor changes, merge with Vojtech's v0.0.3
60 * - verified the lack of HID and report descriptors
61 * - verified that ALL buttons WORK
62 * - fixed d-pad to axes mapping
63 *
64 * 2002-07-17 - 0.0.5 : simplified d-pad handling
d518b2b4
DC		 65 *
66 * 2004-10-02 - 0.0.6 : DDR pad support
67 * - borrowed from the XBOX linux kernel
68 * - USB id's for commonly used dance pads are present
69 * - dance pads will map D-PAD to buttons, not axes
70 * - pass the module paramater 'dpad_to_buttons' to force
71 * the D-PAD to map to buttons if your pad is not detected
bf8cb314
AH		 72 *
73 * Later changes can be tracked in SCM.
