Abstract:
A USB apparatus includes an upstream port, a downstream port, a connection detector and a controller. The connection detector is connected to the upstream port and the downstream port, and is for detecting connection statuses of the upstream port and the downstream port to generate a detecting signal accordingly. The controller is used for controlling the USB apparatus to be operated at a host mode or a hub mode according to the detection signal and control method.
