Query: worked great..then not

had this working fine with a microsoft wireless mouse/keyboard and switching between an XP box and a Linux box. then 1 day it just quit. i crawled behind and unplugged and replugged and powered off and on both machines and nothing. there's nothing to troubleshoot either. no software, no manual switch nothing. reading the manual is useless - it's either gonna work - or not. i'll get a switch with a manual switch next time and probably not one by belkin.
