Keycroc does not work with Cherry Keyboard

Hello,

my Keycroc does not work with Cherry Keyboards. I investigated the problem, and found in "croc_framework" a line which is checking the lsusb command for the keyword "Linux".

But the cherry Keyboard gets registered at the croc as "Bus 005 Device 002: ID 046a:0023 Cherry GmbH CyMotion Master Linux Keyboard G230", so it can't detect it. Could you please fix this issue or tell me how I can fix it? If I adjust the check for "Linux" it unfortunately still doesn't work.

I just realized there is also no /dev/hidraw entry created after plugging in the keyboard.

udevadm monitor gives the following output after pluging in the keyboard:

And here is the output of lsusb:

Any ideas?

Is there maybe a tool to modify the kernel settings while the os is not booted? @Darren Kitchen

That would be perfect. With a framework/firmware that was not updated in more than a year, with plenty of bugs / missing features, it would be nice to be able to do modifications on all levels of the firmware/OS.
