摘要： The present invention provides an apparatus for expanding a serial communication port. The apparatus includes a first serial port, a second serial port and a processing and control module. The first serial port is used to transmit a first signal, and the second serial port is used to transmit a second signal. The processing and control module is coupled between the first serial port and the second serial port. The processing and control module includes a first serial bus host controller, a second serial bus host controller, a data forwarding unit and an expansion unit. The apparatus is connected between an electronic device and multiple peripheral devices, so that via the expansion unit, each peripheral device generates its own communication port on the electronic device.
