The early Opturas didn’t have USB. They relied on the 1394 port to transfer video from tape to hard drive.
I had a situation wherethe Opturahad been talking to my PC via the firewire (4 pin to 4 pin) with no difficulty and suddenly stopped. “DV in” showed on the camera’s monitor but I couldn’t get my software (an old version of Vegas called Video Explosion) to recognize it.
By chance I had purchased another firewire cable and when I tried it in place of the one I had been using, the problem was miraculously solved.
That may not necessarily be the issue here, but if you have another cable it couldn’t hurt to try
