iPhone Not Charging via USB

[myndex]

Weird issue:

My iPhone will charge via the wall adapter - however, when connected to a USB port on my G5, it will charge for a bit, then stop charging (and no longer show the battery icon).

I bought a powered USB hub, and the iPhone will exhibit the same problem when connected to the hub, with the hub further connected to the G5.

It is as if the G5's USB ports are going to sleep - but the computer is set to sleep never.
Does anyone know - is there a plist for the usb ports that might have a setting to cause the USB ports to sleep?

This problem appears to have manifested when I upgraded iTunes to 7.4.2 - I have since downgraded iTunes to 7.3.2, but the problem persists.

Thanks for any help.
