1. A power management method for controlling a first connector with a power pin and a communication pin, the power management method comprising:
recording a first voltage by detecting the communication pin when the first connector is electrically attached to a second connector via the power pin and the communication pin;
detecting the communication pin to generate a second voltage when a bus power is supplied over the power pin;
controlling the bus power in response to a difference between the first and second voltages; and
adjusting a target voltage that the bus power is regulated at by an amount proportional to the difference.
