+ * 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.
