To obtain these values, try: + + sudo udevadm info -a --name=input/eventXX | grep idVendor + sudo udevadm info -a --name=input/eventXX | grep idProduct + +If multiple values come up for each of these, the one you want is the first one of each. + +On other systems which ship with an older udev (such as CentOS), you may need +to set up a rule such as: + + SUBSYSTEM=="input", ENV{ID_CLASS}=="joystick", ENV{ID_INPUT_JOYSTICK}="1" + -- cgit v1.2.3
