Abstract:
Examples are disclosed for automatic downstream to upstream mode switching at a universal serial bus (USB) physical (PHY) layer including activating a switching structure to switch a USB port operating in a downstream mode to an upstream mode based on an attempted attachment by another USB port also operating in a downstream mode. The examples may also include facilitating attachment of the switched USB port now operating in the upstream mode to the other USB port operating in the downstream mode.
