46  *  - get rumble working
47  *  - need USB IDs for other dance pads
48  *
49  * History:
50  *
51  * 2002-06-27 - 0.0.1 : first version, just said "XBOX HID controller"
52  *
53  * 2002-07-02 - 0.0.2 : basic working version
54  *  - all axes and 9 of the 10 buttons work (german InterAct device)
55  *  - the black button does not work
56  *
57  * 2002-07-14 - 0.0.3 : rework by Vojtech Pavlik
58  *  - indentation fixes
59  *  - usb + input init sequence fixes
60  *
61  * 2002-07-16 - 0.0.4 : minor changes, merge with Vojtech's v0.0.3
62  *  - verified the lack of HID and report descriptors
63  *  - verified that ALL buttons WORK
64  *  - fixed d-pad to axes mapping
65  *
66  * 2002-07-17 - 0.0.5 : simplified d-pad handling
67  *
68  * 2004-10-02 - 0.0.6 : DDR pad support
69  *  - borrowed from the XBOX linux kernel
70  *  - USB id's for commonly used dance pads are present
71  *  - dance pads will map D-PAD to buttons, not axes
72  *  - pass the module paramater 'dpad_to_buttons' to force
73  *    the D-PAD to map to buttons if your pad is not detected
74  *
75  * Later changes can be tracked in SCM.
