  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.
