Spent a little time on the phone with CH tech support weenie today myself. My Pro Throttle quit. They told me that I need USB stuff as the MB gameport is choking my input, that the original stuff (pre USB) was only upgraged to 100mhz bus speed at best, and I am running much higher with new system.
hmmm, now contemplating about $300 worth of stuff. bummer.
I really like the CH stuff, but hate to drop those bucks after just building up a new system a month ago.
