 29  * This driver is based on:
 30  *  - information from     http://euc.jp/periphs/xbox-controller.ja.html
 31  *  - the iForce driver    drivers/char/joystick/iforce.c
 32  *  - the skeleton-driver  drivers/usb/usb-skeleton.c
 33  *  - Xbox 360 information http://www.free60.org/wiki/Gamepad
 34  *  - Xbox One information https://github.com/quantus/xbox-one-controller-protocol
 35  *
 36  * Thanks to:
 37  *  - ITO Takayuki for providing essential xpad information on his website
 38  *  - Vojtech Pavlik     - iforce driver / input subsystem
 39  *  - Greg Kroah-Hartman - usb-skeleton driver
 40  *  - XBOX Linux project - extra USB id's
 41  *  - Pekka Pöyry (quantus) - Xbox One controller reverse engineering
 42  *
 43  * TODO:
 44  *  - fine tune axes (especially trigger axes)
 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.
