FYI, in the past, I've experimented with ordinary-user-access based
filtering of the events as obtained from "udevadm monitor", which used
to work happily out of the box:
(in that example, I was running a custom script when the particular
keyboard was attached, I believe).

It's rather a poor man's solution, but the advantage is that it
doesn't require root's privileges for anything, and may suffice for
some use cases (not sure if for yours, Digimer, as well).
