You can follow the symlinks through the '/sys' filesystem. For example the following all point to the same LED. -- simon@womble:~$ ls /sys/class/input/js0/device/device/leds/0003\:054C\:0268.0001\:\:sony1 brightness device max_brightness power subsystem trigger uevent simon@womble:~$ ls /sys/class/leds/0003\:054C\:0268.0001\:\:sony1/ brightness device max_brightness power subsystem trigger uevent simon@womble:~$ ls /sys/bus/hid/devices/0003\:054C\:0268.0001/leds/0003\:054C\:0268.0001\:\:sony1/ brightness device max_brightness power subsystem trigger uevent -- One problem that exists is that many HID devices don't have an (embedded) serial number, so identification can be confused if you have more that one identical device.
