Recently upgraded an old iPhone 3GS to the iPhone 5. Shortly after plugging in the iPhone to a new Windows laptop (usually under 10 minutes), the entire USB hub will reset, disabling all connected devices.
(A USB thumb drive once was the sole survivor, and continued operation even though an external hard drive and USB mouse shut off.)
The laptop is on AC power and has two discrete hubs, one USB 3.0, the other USB 2.0. The same thing happens to either hub, and in both cases, the other is unaffected.
As the 3GS never caused this issue, I am assuming the iPhone 5 draws more heavily on the USB power.
Is there anything I can do to eliminate this issue, other than get an externally-powered hub? (Which I plan to do!)
Update: If I plug the iPhone in fully charged, there seems to be no issue. This seems to indicate that it is indeed related to power draw.
