Running SuperLab 4.07b with response pads shipped before June 2011 on Windows XP. Installed it and its working but only in the USB port I installed it in, not any of the other ports surely it can’t be as restrictive as this?
You’re right, it cannot be that restrictive, even if it wanted to! The only things I can think of are either a problem with your computer or a conflict with another USB device that’s plugged in.
