I bought a Belkin KVM with USB and it was a pain. It kept wanting to change channel, I returned it for a replacement. It to had similar problems, i ended up giving up.
I found getting hold of KVM switches with USB was a pain compared to the cheap readily avaialble ps2 models.
Wow Clayj that Dr.Bott model is like 400 Dollars 😱 I know the belkin were rubbish, but they were only 30... For 400 bucks you can get a decent monitor and keyboard and frig sharing 😀
