Abstract
At least some embodiments are directed to an electronic device port system comprising a first device configured to negotiate power supply contracts from a power source via a universal serial bus (USB) cable. The system also comprises a second device configured to negotiate power supply contracts from the power source via the USB cable when the first device is unable to negotiate power supply contracts from the power source. The second device is configured to activate a switch after the second device negotiates a power supply contract with the power source. The switch is configured to permit the provision of power from the power source to a battery system of the electronic device per the negotiated power supply contract.
