| * 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 |
| * |
| * 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 |
| * |
| * 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 |
