I checked M-Audio's site and checked the listed specs for my computer. They match - both say IEEE 1394a. The TI issue is nowhere on the M-Audio product page.

Oh well, I can always try a new card - that's not hard to do. If that doesn't work, I'm taking it back and going USB2. I didn't want to do that, though. The interface that I would buy is $100 more and I don't think it's $100 better.
