22 * This driver is based on:
23 * - information from http://euc.jp/periphs/xbox-controller.ja.html
24 * - the iForce driver drivers/char/joystick/iforce.c
25 * - the skeleton-driver drivers/usb/usb-skeleton.c
28 * - ITO Takayuki for providing essential xpad information on his website
29 * - Vojtech Pavlik - iforce driver / input subsystem
30 * - Greg Kroah-Hartman - usb-skeleton driver
34 * - fix "analog" buttons (reported as digital now)
35 * - get rumble working
39 * 2002-06-27 - 0.0.1 : first version, just said "XBOX HID controller"
41 * 2002-07-02 - 0.0.2 : basic working version
42 * - all axes and 9 of the 10 buttons work (german InterAct device)
43 * - the black button does not work
45 * 2002-07-14 - 0.0.3 : rework by Vojtech Pavlik
47 * - usb + input init sequence fixes
49 * 2002-07-16 - 0.0.4 : minor changes, merge with Vojtech's v0.0.3
50 * - verified the lack of HID and report descriptors
51 * - verified that ALL buttons WORK
52 * - fixed d-pad to axes mapping
54 * 2002-07-17 - 0.0.5 : simplified d-pad handling
