  45  *  - fix "analog" buttons (reported as digital now)
  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.
