I’ve been putting some thoughts into your setup and have a couple of suggestions to try in the meantime. Would it be possible to please confirm which card model you have? (is it our PEX1394A2V2, or our PEX1394B3) Have you had the chance to verify if our card is still well listed in your Device Manager? (It should show under the “IEEE 1394 Bust Host Controllers” category) And by any chance, would you happen to have any other FireWire device we could test with?
I thank you and look forward to hearing back from you.
