  15 * This driver is based on:
  16 *  - information from     http://euc.jp/periphs/xbox-controller.ja.html
  17 *  - the iForce driver    drivers/char/joystick/iforce.c
  18 *  - the skeleton-driver  drivers/usb/usb-skeleton.c
  19 *  - Xbox 360 information http://www.free60.org/wiki/Gamepad
  20 *  - Xbox One information https://github.com/quantus/xbox-one-controller-protocol
  21 *
  22 * Thanks to:
  23 *  - ITO Takayuki for providing essential xpad information on his website
  24 *  - Vojtech Pavlik     - iforce driver / input subsystem
  25 *  - Greg Kroah-Hartman - usb-skeleton driver
  26 *  - XBOX Linux project - extra USB id's
  27 *  - Pekka P\xC3\xB6yry (quantus) - Xbox One controller reverse engineering
  28 *
  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.
