|
* 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
|
|
*
|
|
* Later changes can be tracked in SCM.
