 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  *
 35  * Thanks to:
 36  *  - ITO Takayuki for providing essential xpad information on his website
 37  *  - Vojtech Pavlik     - iforce driver / input subsystem
 38  *  - Greg Kroah-Hartman - usb-skeleton driver
 39  *  - XBOX Linux project - extra USB id's
 40  *
 41  * TODO:
 42  *  - fine tune axes (especially trigger axes)
 43  *  - fix "analog" buttons (reported as digital now)
 44  *  - get rumble working
 45  *  - need USB IDs for other dance pads
 46  *
 47  * History:
 48  *
 49  * 2002-06-27 - 0.0.1 : first version, just said "XBOX HID controller"
 50  *
 51  * 2002-07-02 - 0.0.2 : basic working version
 52  *  - all axes and 9 of the 10 buttons work (german InterAct device)
 53  *  - the black button does not work
 54  *
 55  * 2002-07-14 - 0.0.3 : rework by Vojtech Pavlik
 56  *  - indentation fixes
 57  *  - usb + input init sequence fixes
 58  *
 59  * 2002-07-16 - 0.0.4 : minor changes, merge with Vojtech's v0.0.3
 60  *  - verified the lack of HID and report descriptors
 61  *  - verified that ALL buttons WORK
 62  *  - fixed d-pad to axes mapping
 63  *
 64  * 2002-07-17 - 0.0.5 : simplified d-pad handling
 65  *
 66  * 2004-10-02 - 0.0.6 : DDR pad support
 67  *  - borrowed from the XBOX linux kernel
 68  *  - USB id's for commonly used dance pads are present
 69  *  - dance pads will map D-PAD to buttons, not axes
 70  *  - pass the module paramater 'dpad_to_buttons' to force
 71  *    the D-PAD to map to buttons if your pad is not detected
 72  *
 73  * Later changes can be tracked in SCM.
