31  *  - the skeleton-driver  drivers/usb/usb-skeleton.c
32  *  - Xbox 360 information http://www.free60.org/wiki/Gamepad
33  *
34  * Thanks to:
35  *  - ITO Takayuki for providing essential xpad information on his website
36  *  - Vojtech Pavlik     - iforce driver / input subsystem
37  *  - Greg Kroah-Hartman - usb-skeleton driver
38  *  - XBOX Linux project - extra USB id's
39  *
40  * TODO:
41  *  - fine tune axes (especially trigger axes)
42  *  - fix "analog" buttons (reported as digital now)
43  *  - get rumble working
44  *  - need USB IDs for other dance pads
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
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
71  *
72  * Later changes can be tracked in SCM.
