I got an Opti-Pac with a USB cable. Everytime I plug it in I get "USB Device not recognized". I have played with the Opti-Pac jumpers, but to no avail. The Serial cable works fine with the Opti-Pac, but I would rather use USB obviously. My USB mouse and USB steering wheel both are recognized fine, but not the Opti-Pac.
Any ideas? Thanks.
