This is to help improve overall interoperability. I know that most xbox 360 devices can directly define the device type with the descriptors. That said, Two of the mappings that can work are MAP_FLIGHT_STICK and MAP_RACING_WHEEL. In the case of the MAP_RACING_WHEEL the following look reasonable enough... ABS_WHEEL ( X axis on Left stick ) ABS_GAS ( Left trigger ) ABS_BRAKE ( Right Trigger ) in the case of MAP_FLIGHT_STICK, the following is needed... PITCH/ROLL - Axis of Left stick POV Hat - Right stick Rudder - Left Trigger Throttle - Right Trigger. -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
