<p>Methods and apparatus for intelligently powering an electronic device are provided. In one embodiment of the invention, a systems management controller controls a power interface to intelligently negotiate power distribution with a peer, client, or a host device. The primary data path is unaffected by the system management controller communications. Various aspects of the present invention are demonstrated with respect to an exemplary implementation of a unified interface, consisting of an optical link (data path) and a USB link (power). As described, one exemplary embodiment of the invention provides a device with power at levels which are much increased over prior art USB solutions.</p> |
