My impression that up = positive and down = negative seems to be a personal bias since the first application that I tried it with (i.e. joymouse) seems to interpret it in the opposite manner. In any case here's an updated wireless 360 patch that leaves the polarity as it is and also includes support for setting the LEDs of the wireless controllers which of course is different than how the wired variety does it. -Brian Signed-off-by: Brian Magnuson <bdmagnuson@gmail.com> --- drivers/input/joystick/xpad.c | 135 +++++++++++++++++++++++++++++++++++++++-- 1 files changed, 130 insertions(+), 5 deletions(-) diff --git a/drivers/input/joystick/xpad.c b/drivers/input/joystick/xpad.c index 664c765..7c5947c 100644 --- a/drivers/input/joystick/xpad.c +++ b/drivers/input/joystick/xpad.c @@ -93,6 +93,7 @@ #define XTYPE_XBOX 0 #define XTYPE_XBOX360 1 +#define XTYPE_XBOX360W 2 static int dpad_to_buttons; module_param(dpad_to_buttons, bool, S_IRUGO); @@ -109,6 +110,7 @@ static const struct xpad_device { { 0x045e, 0x0289, "Microsoft X-Box pad v2 (US)", MAP_DPAD_TO_AXES, XTYPE_XBOX }, { 0x045e, 0x0285, "Microsoft X-Box pad (Japan)", MAP_DPAD_TO_AXES, XTYPE_XBOX }, { 0x045e, 0x0287, "Microsoft Xbox Controller S", MAP_DPAD_TO_AXES, XTYPE_XBOX }, + { 0x045e, 0x0719, "Xbox 360 Wireless Receiver", MAP_DPAD_TO_BUTTONS, XTYPE_XBOX360W }, { 0x0c12, 0x8809, "RedOctane Xbox Dance Pad", MAP_DPAD_TO_BUTTONS, XTYPE_XBOX }, { 0x044f, 0x0f07, "Thrustmaster, Inc.
