I have a Darksector USB keyboard connected to my RPi4 LibreELEC(9.2.1) mediabox. This keyboard blacklight is connected (by hardware) to scroll lock led. Therefore, I would like to switch the scroll Lock LED somehow. I have tried through:
echo 1 > /sys/class/input/input0/input0:scrolllock/brightness
but no avail(maybe the kernel miss some hooks).
There is no xset (as there is no X server in LibreElec)
There is a python command in evdev module, that can switch LED but it is not present in LibreELEC.
Please add support for led switch.
