The problem I have heard of relates to "what happens if the machine boots 
with the KVM switched to another machine?" The KVM may need to pretend 
there is a keyboard connected at that point. You certainly can't tell by 
looking at the box, but the Trendnet TK-407 I have (which is a 4-port USB 
KVM from the vendor you mention) works fine with FreeBSD and Windows. We 
haven't tested the mouse in FreeBSD. Since any USB KVM would be fairly 
recent, you might just want to take a chance.

Solaris Sparc systems had worse problems.
