The 4 port OmniCube is $89.99 retail, I wouldn't call that cheap.
Even if I put the OmniCube on port 2 (which the NetBSD machine is
setup to use), and boot it up, NetBSD doesn't recognise the PS/2
mouse. If I switch back to port 1 (Win2K machine), mouse works
fine. This thing does remember the mouse and keyboard configurations.
The documentation says that it is certified for Win95, Win98, WinNT,
Win2K, Novell Netware 5, TurboLinux and all Linux Distributions.
In fact, I had a Linux Mandrake system here and it worked fine with
the KVM switch.
FWIW, I've also tried a couple of different mouses on the KVM switch
with the same results.
