Unfortunately I can just say I have the same problem with a Sony DCR-PC110E and Imac. Firewire works fine, usb download of pics is an endless loop though directories without anything to download. It is obviously a usb driver problem , but for the moment I did not find a new one. By the way on Windows '98 it works fine. If I'll find a solution I'll post it here.(posted 8034 days ago)
