*
* This driver is based on:
* - information from http://euc.jp/periphs/xbox-controller.ja.html
* - the iForce driver drivers/char/joystick/iforce.c
* - the skeleton-driver drivers/usb/usb-skeleton.c
* - Xbox 360 information http://www.free60.org/wiki/Gamepad
* - Xbox One information https://github.com/quantus/xbox-one-controller-protocol
*
* Thanks to:
* - ITO Takayuki for providing essential xpad information on his website
* - Vojtech Pavlik - iforce driver / input subsystem
* - Greg Kroah-Hartman - usb-skeleton driver
* - XBOX Linux project - extra USB id's
* - Pekka Pöyry (quantus) - Xbox One controller reverse engineering
*
* TODO:
* - fine tune axes (especially trigger axes)
* - fix "analog" buttons (reported as digital now)
* - get rumble working
* - need USB IDs for other dance pads
*
* History:
*
* 2002-06-27 - 0.0.1 : first version, just said "XBOX HID controller"
*
* 2002-07-02 - 0.0.2 : basic working version
* - all axes and 9 of the 10 buttons work (german InterAct device)
* - the black button does not work
*
* 2002-07-14 - 0.0.3 : rework by Vojtech Pavlik
* - indentation fixes
* - usb + input init sequence fixes
*
* 2002-07-16 - 0.0.4 : minor changes, merge with Vojtech's v0.0.3
* - verified the lack of HID and report descriptors
* - verified that ALL buttons WORK
* - fixed d-pad to axes mapping
*
* 2002-07-17 - 0.0.5 : simplified d-pad handling
*
* 2004-10-02 - 0.0.6 : DDR pad support
* - borrowed from the XBOX linux kernel
* - USB id's for commonly used dance pads are present
* - dance pads will map D-PAD to buttons, not axes
* - pass the module paramater 'dpad_to_buttons' to force
* the D-PAD to map to buttons if your pad is not detected
*
* Later changes can be tracked in SCM.
