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