Iphone 5 does nothing when plugged into pc
My pc is windows 8, iTunes 10.7, i have iOS 6.0.2. When i plug in the lightning cable to the pc and iPhone, it does absolutely nothing, doesn't start charging, doesn't install drivers, doesn't sync to iTunes, nothing. Bonjour and apple mobile service are running and have been restarted many times, so has the pc. The cable works fine charging from mains, how do i connect it to pc?
