I had the same error with a friends portable USB iPod wannabe. I could copy a single small clip from iMovie but that was it. Even a large 13MB QT file would not work. I'm Kind of glad it did not cause it would have taken approx six hours to copy (as opposed to minutes with FW). Anyone who has tried to use USB for video work probably now owns a Firewire enclosure. To directly answer your question, no I was never able to make that USB device work. FW is my answer. -Preston FYI- I picked up my enclosure for under 50 bucks. watch places like computergeeks.com. they get them in on occasion, but make sure it has the Oxford 911 chipset.
