Abstract
A Universal Serial Bus (USB) dock includes ports, a processor, and instructions to cause the processor, below a level of an operating system running applications and accessing the USB dock, identify a first port of the plurality of ports as a priority port. The processor may be further caused to detect a connection to the dock. The processor may be further caused to determine whether a candidate port to which the connection is made is the priority port. The processor may be further caused to, based on a determination that the candidate port is the priority port, recover power from other ports and advertise power capabilities of the priority port to a USB element connecting to the dock.
