I have been using this Sabrent KVM switch for a few years now. Generally it works fine, but sometimes a laptop plugged into it won't recognize it and I have to unplug from it both computers and both power supplies. I would like to find a replacement, both for that, and one that has some extra USB ports for a camera etc. Does anyone know of one?

I'm looking to connect two laptops; most of the ones I find are for a desktop and a laptop or two desktops, for some reason.
