Port Class

class PortClass : public Acroname::BrainStem::EntityClass

Port Class: The Port Entity provides software control over the most basic items related to a USB Port. This includes everything from the complete enable and disable of the entire port to the individual control of specific pins. Voltage and Current measurements are also included for devices which support the Port Entity.
