Lists all SUBSYSTEM=hid devices, including the respective hidraw and evdev nodes. Note that this takes a shortcut in the udev handling: in theory we *should* compare the hidraw/evdev parent device with our hid device. In practice, checking if the devpath starts with the same substring is good enough. Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net>
