I just purchased a new MBP 15," and I'm having a problem that's driving me crazy. I can't get my Metric Halo ULN-2 audio interface to talk to the MBP via the new MBP Firewire 800 port. I've tried a cable that goes from FW800 to FW400. I've purchased adapters Sonnnet 6-pin to 9-pin adapters that will allow me to use the standard FW400 cables with the MBP. Nothing works. Now here's the thing. The MBP port clearly works. I can plug in a drive that works properly FW800 > FW800. Further, the cable with the adapter attached is carrying signal to allow a drive plugged into the MH ULN-2 to be recognized. I just can't get Logic to see the MH ULN-2. Anyone have any ideas?
