FWIW, it seems things work for many people, but something still is not
completely right:

--- Comment #47 from Mark Blakeney ---
@Juha, kernel 6.3.7 adds the 2 patches intended to fix this bug and the
startup delay is now gone. However, I have had 2 cases over the last 5
days in which I have been running 6.3.7 where my mouse fails to be
detected at all after startup. I have to pull the Logitech receiver
out/in to get the mouse working. Never seen this issue before so I
suspect the patches are not right.

Ciao, Thorsten
