Claim Text:
1. An electronic device, comprising: a universal serial bus (USB) connector for receiving a USB cable for connection to an associated high voltage adapter, the USB connector comprising a first conductive structure for electrical connection to a first data signal conductor of the USB cable, a second conductive structure for electrical connection to a second data signal conductor of the USB cable, a third conductive structure for electrical connection to a first power conductor of the USB cable, and a fourth conductive structure for electrical connection to a second power conductor of the USB cable; a load operatively coupled to receive electrical power via the third and fourth conductive structures at a nominal voltage level or at least one of a plurality of high voltage levels above the nominal voltage level; a transmit circuit coupled with the first and second conductive structures of the USB connector, the transmit circuit selectively operative in first and second transmitter states and comprising: a processor programmed to selectively place the transmit circuit in the first transmitter state to disable the transmit circuit to instruct the associated high voltage adapter to provide electrical power to the electronic device via the USB cable at the nominal voltage level or to selectively place the transmit circuit in the second transmitter state to instruct the associated high voltage adapter to provide electrical power to the electronic device via the USB cable at a first one of the high voltage levels.
