Method of Power Management for a Hub with a Plurality of Usb-c Ports
21 Dec 23
A method of power management for a hub having a plurality of Universal Serial Bus (USB)-C ports includes: allocating a guaranteed power budget to each USB-C port of the hub, wherein one of the USB-C ports has a higher power priority and the other USB-C ports have a lower power priority; reducing the guaranteed power budget allocated to a USB-C port with the lower power priority if measured power for that USB-C port is below its currently guaranteed power budget by a predetermined amount; and offering additional power budget to the USB-C port with the higher power priority if the guaranteed power budget allocated to a USB-C port with the lower power priority was previously reduced.
