11. A device configured to provide a universal serial bus (USB) interface, the device comprising:
a USB receptacle comprising a plurality of pins;
a power circuit configured to generate at least one voltage;
a switch configured to electrically connect a first pin of the plurality of pins and the power circuit in response to a switch control signal that is activated; and
a port controller configured to detect an impedance between at least two pins of the plurality of pins and generate the switch control signal based on the detected impedance.
