DELEGATION OF UNIVERSAL SERIAL BUS POWER AMONG MULTIPLE PORTS

摘要

A circuit includes a port manager to monitor requested port power from each of a plurality of universal serial bus (USB) ports. The port manager sets a separate port variable for each of the USB ports that indicates a priority in which each of the USB ports have requested port power. A controller monitors the separate port variables from the port manager for each of the USB ports. The controller delegates power to the USB ports based on the priority assigned by the port manager.
