Port Enable

The “port-enable” interfaces enable turning a specific port on or off. When a port is enabled, both power and data lines become active. Conversely, power and data lines get disconnected when the port is disabled, simulating the removal of a USB cable. Note that for USB-C ports, the CC line will be activated to negotiate the appropriate power level for Vbus power. Vbus will not be active until proper CC negotiation has occurred.
