 |  *  - 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. |
