KVM PS@ and usb

Hello,

I want to use a KVM with a PS2 VX0 and a Dell that does not have ps2. Is there an addon that would enable usb mouse and keboard to be used with the VX0? Usb to ps2 and ps2 to usb adapters do not seem to work with KVMs.

Or some other solution (other than using a PS2 PC).

Thanks.
