Abstract

The hub is electrically connected to a first electronic device and a display outside the hub. The hub comprises a circuit board, a MCU, a front type-C transmission line, a first USB type-C output terminal, a first input controller, a first output controller, a first output multiplexer and a USB hub processor. The front type-C transmission line comprises a power transmission line, a first data transmission line set and a second data transmission line set. The first USB type-C output terminal is electrically connected between the power transmission line and the first type-C transmission line. The first input controller is disposed on the circuit board and electrically connected to the MCU and the first electronic device. The first output controller is disposed on the circuit board and electrically connected between the MCU and the first USB type-C output terminal. A connecting status of the first type-C transmission line and the first USB type-C output terminal is detected by the first output controller.
