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
