0022  * Thanks to:
0023  *  - ITO Takayuki for providing essential xpad information on his website
0024  *  - Vojtech Pavlik     - iforce driver / input subsystem
0025  *  - Greg Kroah-Hartman - usb-skeleton driver
0026  *  - XBOX Linux project - extra USB id's
0027  *  - Pekka Pöyry (quantus) - Xbox One controller reverse engineering
0028  *
0029  * TODO:
0030  *  - fine tune axes (especially trigger axes)
0031  *  - fix "analog" buttons (reported as digital now)
0032  *  - get rumble working
0033  *  - need USB IDs for other dance pads
0034  *
0035  * History:
0036  *
0037  * 2002-06-27 - 0.0.1 : first version, just said "XBOX HID controller"
0038  *
0039  * 2002-07-02 - 0.0.2 : basic working version
0040  *  - all axes and 9 of the 10 buttons work (german InterAct device)
0041  *  - the black button does not work
0042  *
0043  * 2002-07-14 - 0.0.3 : rework by Vojtech Pavlik
0044  *  - indentation fixes
0045  *  - usb + input init sequence fixes
0046  *
0047  * 2002-07-16 - 0.0.4 : minor changes, merge with Vojtech's v0.0.3
0048  *  - verified the lack of HID and report descriptors
0049  *  - verified that ALL buttons WORK
0050  *  - fixed d-pad to axes mapping
0051  *
0052  * 2002-07-17 - 0.0.5 : simplified d-pad handling
0053  *
0054  * 2004-10-02 - 0.0.6 : DDR pad support
0055  *  - borrowed from the XBOX linux kernel
0056  *  - USB id's for commonly used dance pads are present
0057  *  - dance pads will map D-PAD to buttons, not axes
0058  *  - pass the module paramater 'dpad_to_buttons' to force
0059  *    the D-PAD to map to buttons if your pad is not detected
0060  *
0061  * Later changes can be tracked in SCM.
