Booting up and external KB with M1 Mac Mini (USB3, USB-C, wired) problems at SDDM

[resistorsoftware]

I have a Mac Mini with an external KB. It has both wired and BT connections. The struggle is, when logging in to Asahi, it ONLY responds to a KB wired in as the older USB 3 port on the back of the Mac Mini. Once logged in, the Asahi seems to be able to remember I had two BT devices connected from a previous session. So my MX Mouse on BT and external KB with BT are "connectable".

TL:DR; an external BT KB, also wired in as USB-C to M1 Mac Mini does not work on the SDDM login screen. Only a KB wired in as USB-3 to Mac Mini works.

Would be nice if the SDDM screen was capable of connecting to the BT KB and Mouse that suddenly are available once login completes and the desktop is loaded. If not BT, at least talk to the USB-C wired KB.

Is there something easy for me to change to get this KB working at SDDM?
