A USB hub includes a main body, an illumination module, a power module, and at least one USB port. The illumination module is disposed within the main body for emitting a light beam, wherein the light beam is transmissible through the main body. The power module is disposed within the main body and electrically connected with the illumination module for providing electric energy to the illumination module. The USB port is installed in the main body. The USB port includes a detecting terminal, and the detecting terminal is electrically connected with the power module. The detecting terminal issues a detecting signal according to a result of judging whether the USB port is connected with a USB plug of an external electronic device. According to the detecting signal, the power module selectively provides the electric energy to the illumination module or stops providing the electric energy to the illumination module. |
