I can't make the detachable keyboard to work once i boot into latest Mint life USB (to test compatibility for later making it dual boot with Win 11).
Keyboard works perfectly fine in Windows, Bios, boot menu, all the way to the GRUB but once i get to the desktop environment, it doesn't react to any input.

I have tried following:
  • Boot with following GRUB params
    • - Put keyboard port into non-translated mode.
    • i8042.dumbkbd - Pretend that controller can only read data from keyboard and cannot control its state .
  • Mint 21.2 with "LTS" kernel
  • Mint 21.2 EDGE with latest Kernel
External USB keyboard works well, so far no other issue detected.
The indicates device should work with Linux.

Any idea what's wrong and how to make it work ? Please mind i have not yet installed the Linux on the device because of the mentioned issue. I need to verify system works before installing it (there's more fiddling needed on windows side to do that ).
