Abstract: A universal serial bus (USB) dock includes USB ports, each configured to connect to a respective USB element. The USB dock includes a circuit communicatively coupled to the USB ports and configured to determine a first temperature measurement in the USB dock, determine a power demand for each USB element connected to the USB ports, determine an allocation of power for the USB elements, and, based on the first allocation of power, provide less than the power demand for one or more of the USB elements based upon a total power demand by the USB elements and the first temperature measurement.

Abstract: An apparatus includes a processor and a machine-readable medium coupled to the processor and comprising instructions. The instructions, when loaded into the processor and executed, configure the processor to identify that a USB element has attached to a USB hub at a port, classify the USB element according to power operations of the USB element, and assign an upstream or downstream setting of the port based upon the classification of the USB element based on power operations of the USB element. The instructions may further configure the processor to classify the USB element as only a producer of power, evaluate whether an enumeration process is initiated within a timeout period, and if so, assign the USB element as a USB host.

Abstract: A universal serial bus (USB) hub includes an upstream port configured to be communicatively coupled to a USB host, a downstream port, and a USB hub core circuit. The circuit is configured to determine a detachment from the downstream port, determine whether a USB element has reattached to the downstream port in USB mode, and, based on a determination that the USB element has reattached to the downstream port in USB host mode, perform USB multi-host bridging for the USB host and the USB element.
