Check to see if your computer has a Powered USB port (these usually output anywhere from 1 to 2 Amps).
Screen is off. Sidesync only works with the screen off... once you turn it on, the phone is automatically disconnected from the pc.
I have all kinds of USB ports, blacks and blues, etc.. but the phone gets 0.5 amps from all of them (measured via cool tool). Any way to force 1 Amp?
