I'm having the same problem. Just got an Asus, Windows 7 64-bit. When I'm multitasking, switching windows, typing, mousing, footpedalling, my foot pedal will freeze and I also have to restart. Didn't have this problem with XP. Just found thread so will have to also try the suggestions above. Don't see that there is a driver update. Pedals are supposed to be compatible with Windows 7. I have an IN-USB-2 and an IN-USB-1, same problem with both. Foot pedal is plugged directly into USB, not through a hub.
