摘要： A bridging device with power-saving function includes first and second interfaces, first and second physical layer processing devices, and a controller. The first interface is utilized for coupling a first external device complying with the first interface. The first external device receives a device request signal, and accordingly sends back a device response signal through the first physical layer processing device. The second interface is utilized for coupling a second external device complying with the second interface. The controller is coupled between the first and the second physical layer processing device for transmitting the device request signal with the predetermined frequency to the first physical layer processing device in order to receive the device response signal. When the controller does not receive the device response signal, the controller turns the second physical layer processing device off.

The USB peripheral device contains a card connection unit and a USB microprocessor. By judging whether the card connection unit is inserted with a card device, the USB microprocessor is determined to transmit the data or not with the basic system of processor. If one card device is inserted into the card connection unit, the USB microprocessor outputs the corresponding class code according to the device class of the card device for the basic system of processor distinguishing and confirming said class code. Therefore, dynamically changing the device class in accordance with various card devices is achieved.

摘要： The present invention discloses a computer peripheral apparatus. The computer peripheral apparatus includes an USB hub, at least one build-in card reader, and a controller. Each build-in card reader is electrically connected to one built-in downstream port of the USB hub. The controller connects to the USB hub and the build-in card reader to monitor the connection requirement of the build-in card reader. When the controller determines the build-in card reader does not need to be kept connected, the controller sets the status of its corresponding built-in downstream port as a “first status,” which defines the corresponding built-in downstream port is not connected. Thus, the computer system is informed that the built-in downstream port is not connected. Therefore, if there are no USB devices connecting to other downstream ports of the USB hub, the entire computer peripheral apparatus can enter into hibernation mode, thereby lowering the power consumption
