Read my post at the bottom of page 1. It has to do with how much power can be sent with the USB vs FireWire connection.Amie said:Ah ... I see! Well, that explains it, then. Though I'm not sure that I fullly understand the difference between connecting an iPod via USB port and connecting it via FW port. Sure, I know they're different ports, but what's the functional difference? I do iPod-syncing, adding songs, removing songs, etc. via USB. Doesn't FW basically do the same thing?
