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.
