@davidrevoy I have somewhat accepted this fate and tried to use it with the input remapper program. As for the tablet I wish to see udev-hid-bpf work with default Debian kernel. that would take away some burden of keeping the liquorix kernel up to date for security reasons.
@raghukamath Oh yes, this Debian policy to not get the bpf system in their default kernels is really a pain...
I haven't retried the input-remapper in age with this device and forgot about it: can it bypass the two key shortcut and assign instead only a single keypress? (eg. reassigning the Ctrl+O to a simple B?)
