27 * This driver is based on:
28 * - information from http://euc.jp/periphs/xbox-controller.ja.html
29 * - the iForce driver drivers/char/joystick/iforce.c
30 * - the skeleton-driver drivers/usb/usb-skeleton.c
31 *
32 * Thanks to:
33 * - ITO Takayuki for providing essential xpad information on his website
34 * - Vojtech Pavlik - iforce driver / input subsystem
35 * - Greg Kroah-Hartman - usb-skeleton driver
36 * - XBOX Linux project - extra USB id's
37 *
38 * TODO:
39 * - fine tune axes (especially trigger axes)
40 * - fix "analog" buttons (reported as digital now)
41 * - get rumble working
42 * - need USB IDs for other dance pads
43 *
44 * History:
45 *
46 * 2002-06-27 - 0.0.1 : first version, just said "XBOX HID controller"
47 *
48 * 2002-07-02 - 0.0.2 : basic working version
49 * - all axes and 9 of the 10 buttons work (german InterAct device)
50 * - the black button does not work
51 *
52 * 2002-07-14 - 0.0.3 : rework by Vojtech Pavlik
53 * - indentation fixes
54 * - usb + input init sequence fixes
55 *
56 * 2002-07-16 - 0.0.4 : minor changes, merge with Vojtech's v0.0.3
57 * - verified the lack of HID and report descriptors
58 * - verified that ALL buttons WORK
59 * - fixed d-pad to axes mapping
60 *
61 * 2002-07-17 - 0.0.5 : simplified d-pad handling
62 *
63 * 2004-10-02 - 0.0.6 : DDR pad support
64 * - borrowed from the XBOX linux kernel
65 * - USB id's for commonly used dance pads are present
66 * - dance pads will map D-PAD to buttons, not axes
67 * - pass the module paramater 'dpad_to_buttons' to force
68 * the D-PAD to map to buttons if your pad is not detected
