At my desk I have a a desktop PC and a docking station for a laptop. I use a USB KVM switch to control both computers with a single mouse/keyboard. Occasionally (about 20% of the time) when I switch back to the laptop it does not respond to the mouse or keyboard. Nothing I have found to do short of rebooting the laptop will get it to respond to the peripheral keyboard and mouse. This does not appear to be an effect of the docking station since I have been able to reproduce the problem after plugging the laptop directly into the KVM. The laptop is an HP dv1000 running Windows XP. Any suggestions on what I can do to prevent the problem or to cure it without having to reboot?
