KVMs and keyboards with NKRO

I just bought a Topre Realforce R2 keyboard, and my trusty old ConnectPro UD-12+ DVI KVM doesn’t recognize it: the KVM’s LEDs blink furiously, and the connected PCs don’t receive any keystrokes. The ConnectPro tech thinks the KVM cannot handle the keyboard’s NKRO feature, which unfortunately cannot be disabled. I wonder if I’d have better luck with one of the LevelOne KVMs. The LevelOne site says these KVMs can support high-end mechanical keyboards, so I’m thinking it is worth a try.

Thanks for any suggestions
