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
