Abstract
A USB hub device includes an upstream port and a downstream port. A USB control circuit of the USB control circuit includes an upstream interface; a downstream interface; a first switch circuit for coupling with the upstream port; a second switch circuit for coupling with the downstream port; a control signal transmission interface coupled with the first switch circuit and the second switch circuit; and a control unit, coupled with the control signal transmission interface, configured to operably control the first switch circuit and the second switch circuit through the control signal transmission interface, so that the first switch circuit selectively couples one of the upstream interface and the second switch circuit with the upstream port, while the second switch circuit selectively couples one of the downstream interface and the first switch circuit with the downstream port.
