wireless mouse on 9.1

[Zoran Kolic]

I had usb switch to share keyboard and mouse for two nodes, of
which freebsd worked flawlessly, but openbsd disconnected quite
often and made a lot of antics in X. After all, I dismembered
the configuration and now I have 2 kb-s and 2 mice. A lot of
wires on the table. The plan would be to get not too expensive
wireless mouse for freebsd node.
Reading forums I found a lot of people having problem with
those kind of mice. Could someone recommend one what is known
to work on branch 9? For some reason I prefer logitech. And I
assume that usb dongle works on hardware level and does not need
anything to work?
Best regards
