41 * TODO:
Dominic Cerquettideb8ee42006-10-10 14:42:48 -070042 * - fine tune axes (especially trigger axes)
Linus Torvalds1da177e2005-04-16 15:20:36 -070043 * - fix "analog" buttons (reported as digital now)
44 * - get rumble working
Dominic Cerquettideb8ee42006-10-10 14:42:48 -070045 * - need USB IDs for other dance pads
Linus Torvalds1da177e2005-04-16 15:20:36 -070046 *
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
Dominic Cerquettid518b2b2006-10-20 14:51:45 -070065 *
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
Anssi Hannulabf8cb312008-04-03 16:19:10 -040072 *
73 * Later changes can be tracked in SCM.
