Some interesting news about iPhone sync speed and the use of USB hubs. I seriously doubt there is an issue with USB 2.0 specification so this must be related more towards the USB stack the iPhone uses with their chip. Apparently having the iPhone connected to a USB hub for sync will slow the process. To throw more flame on the fire, if you have a USB 1.0 device [like a keyboard or mouse] also connected to the USB hub, the sync grinds to a halt.
You’ll could definitely run into problems if it’s a self-powered USB hub, so try one with a separate power connector/source.
Word on the proverbial street is that most who did a direct connect from iPhone to Mac or PC had a much faster sync time – down to a couple of minutes.
How about you? Have you tried with or without the hub? Comment.
