  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.
