I'm looking for a KVM that can support machines with PS/2 ports and machines with USB ports in the same switch.

I have a Dell 1800 (PS/2) and a Dell 1900 (USB with adapter) and the 1900's KB and mouse will not work with the new KVM I got, though it does work with an adapter (PS/2 mouse & KB in, USB out) connected directly to the server. I have checked with the manufacturer that they will not support my configuration.

What KVMs support both PS/2 and USB?

We use Linkskey KVMs in our server room. They seem to work well and don't cost an arm and a leg. Here's the 8-port version of what we have: LINKSKEY LKV-9308

Check out the combo models of KVM from IOGEAR. They all support both USB and PS/2, depending on the cable type used. Different sizes from 2 to 16 ports. I've had good experiences using their products and haven't run in to any compatibility issues yet.

IOGear swears up and down that mixed ports are not supported by any of their products. Facepalm moment is that we have one of IOGear's rack-mounted 8 port PS/2 units and it works with a USB dongle. I must have been stupid for thinking that this would work with a new switch. –  dmoisan Jul 1 '09 at 15:45

I don't have a recommendation, but a suggestion that you try a different USB adapter. Our older Raritan Paragon KVM didn't seem to work with several USB adapters, but works perfectly with some.

Here is a USB adapter that seems to work with all PS2 KVMs that I have worked with.

We use the 8 port version of the Belkin OmniView PRO3.
