Abstract: 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.

Abstract: A storage may store machine-readable instructions for execution by a processor. Execution of the machine-readable instructions may cause the processor to receive an update capsule via a firmware update interface. The update capsule may include a device identifier and a payload. The payload may include data that is different from a firmware update. Execution of the machine-readable instructions may cause the processor to execute a virtual device handler, based on the device identifier, to process the payload.
