I use a Microsoft wireless keyboard/mouse combo with a Belkin KVM, but the
wireless receiver is plugged in with the PS2 connectors. My KVM isn't USB, but I
would imagine that the problem could be that the receiver(s) you tried need more
power than the KVM can deliver or a driver is needed for the receiver to
function.

Interesting - I just got back to playing with this. I have found
that the wireless keyboard works just fine when I plug the its
receiver's USB into a rear input on the KVM. Won't work using the
KVM's front USB. That's a little odd because the wired keyboard being
replaced will work with its USB plugged into the KVM's front or rear.
Oh well, I can work with the wireless keyboard connecting with the
rear USB on the KVM. No difference to me, really.
Thanks for your interests you two.
