I'm not sure if it really belongs here or not, but here's my cautionary tale:

The StarTech SV431USB keeps disconnecting from slave machines when switching. It'll just stop responding to both mouse and keyboard until the USB cable from the KVM is unplugged and plugged in again. Not necessarily anything to do with the KVM, just FYI.

Logitech RX700 mice seem to ship with *different* RF keys. So I can't find any way to make them all slave off of one mouse. I tried resetting and so on, but no luck. A quick google didn't turn up anything on getting the keys to sync to a new mouse, either. AFAICT, I'm screwed and need to buy new mice or buy the usb mouse splitter from Vetra. I've got a support question in to Logitech about this, but no response yet.

It might be useful to get the precise brands that people have had success with (or in this case, failure).
