How to find value C for specific system?

[yonazdk]

The script works for the mouse, but not for the keyboard.
Either the ID is wrong, but I've tested everything from 00-99, og the C value is wrong, but I can't figure out how to verify it.

Any assistance would be very welcome :)

I'm on Windows.

The easiest way I was able to find out was with busdog and Logitech Options+ with Logitech Flow.
However, to only see value C you could also make use of solaar and look for the command number in front of the "CHANGE HOSTS" command.
e.g.
9: CHANGE HOSTS -> 0x09
12: CHANGE HOSTS -> 0x0c
