  • Patent number: 10444808
    Abstract: A USB control apparatus is connected between a power supply and an external interface, and the USB control apparatus includes a first connection port connected to the power supply; a second connection port connected to the external interface; a control unit connected to the first connection port; and a first conversion unit connected between the control unit and the second connection port. The control unit detects a power source outputted from the power supply and outputs first information to the first conversion unit. The first conversion unit detects the type of a connection port of the external interface. The first conversion unit converts the first information into second information corresponding to the connection port of the external interface to the second connection port.
