iPhone Lightning Dock charge/not charge/charge
Just got the iPhone Lightning Dock, plugged in to my USB lightning cable directly into my Mac Pro then to the Dock. When I have the phone (or iPad mini) connected. It vibrates and starts charging... then, about a minute later, it vibrates again and starts charging... Do I have a faulty Dock? Using the lighting cable directly works fine.
Mac Pro, OS X Mavericks (10.9.3)
