  35  * Thanks to:
  36  *  - ITO Takayuki for providing essential xpad information on his website
  37  *  - Vojtech Pavlik     - iforce driver / input subsystem
  38  *  - Greg Kroah-Hartman - usb-skeleton driver
  39  *  - XBOX Linux project - extra USB id's
  40  *
  41  * TODO:
  42  *  - fine tune axes (especially trigger axes)
  43  *  - fix "analog" buttons (reported as digital now)
  44  *  - get rumble working
  45  *  - need USB IDs for other dance pads
  46  *
  47  * History:
  48  *
  49  * 2002-06-27 - 0.0.1 : first version, just said "XBOX HID controller"
  50  *
  51  * 2002-07-02 - 0.0.2 : basic working version
  52  *  - all axes and 9 of the 10 buttons work (german InterAct device)
  53  *  - the black button does not work
  54  *
  55  * 2002-07-14 - 0.0.3 : rework by Vojtech Pavlik
  56  *  - indentation fixes
  57  *  - usb + input init sequence fixes
  58  *
  59  * 2002-07-16 - 0.0.4 : minor changes, merge with Vojtech's v0.0.3
  60  *  - verified the lack of HID and report descriptors
  61  *  - verified that ALL buttons WORK
  62  *  - fixed d-pad to axes mapping
  63  *
  64  * 2002-07-17 - 0.0.5 : simplified d-pad handling
  65  *
  66  * 2004-10-02 - 0.0.6 : DDR pad support
  67  *  - borrowed from the XBOX linux kernel
  68  *  - USB id's for commonly used dance pads are present
  69  *  - dance pads will map D-PAD to buttons, not axes
  70  *  - pass the module paramater 'dpad_to_buttons' to force
  71  *    the D-PAD to map to buttons if your pad is not detected
  72  *
  73  * Later changes can be tracked in SCM.
