Abstract: A hub including an up-stream port, at least one down-stream port, a state-determining unit, and a control unit is provided. The up-stream port is configured to be coupled to a host device. The down-stream port is configured to be coupled to at least one peripheral device. The state-determining unit is coupled to the down-stream port and generates a determination result according to a level of a pin of the down-stream port. The control unit is coupled between the up-stream port and the state-determining unit. When the host device sends a sleep request, the control unit determines whether the peripheral device is operating in a specific mode according to the determination result. When the peripheral device is operating in the specific mode, the control unit provides an unready response to the host device.

Abstract: An apparatus is provided for coupling a Universal Serial Bus (USB) device and a USB host. The apparatus includes a memory and a controller. The memory includes one or more descriptor entries. The controller is configured to obtain a descriptor of the USB device upon detection of the USB device on a USB bus, and compare the descriptor to a specific descriptor entry to generate a comparing result. Then the controller enables or disables a link path between the USB host and the USB device according the comparing result.

Abstract: A transmission system receiving a first token packet and a second token packet is disclosed. The transmission system is coupled to a first peripheral device and a second peripheral device. The transmission system includes an upstream port to receive the first and the second token packets. A first transmission path occurs between the upstream port and the first peripheral device. A second transmission path occurs between the upstream port and the second peripheral device. The transmission system analyzes the first and the second token packets. The first token packet includes information corresponding to the first peripheral device. When the second token packet includes information corresponding to the first peripheral device, the transmission system disables the second transmission path.

Abstract: A data transmission system and method are provided. The data transmission system includes a first link partner and an optical transceiver unit. The first link partner includes a controller. When the first link partner is in an abnormal operation mode, the controller controls the first link partner to exit from the abnormal operation mode. The optical transceiver unit is coupled between the first link partner and a second link partner and performs data transmission between the first link partner and the second link partner. According to the data transmission system and method, one link partner can accurately detect whether another link partner is coupled to the one link partner through an optical transceiver unit. Accordingly, data transmission between the two link partners can be stably performed through the optical transceiver unit.

Abstract: A delay fault testing apparatus includes a scan device having a first input for receiving a data to the core under test, an update device including an input electrically connected to a first output of the scan device, a first multiplexer including a first input electrically connected to the output of the scan device, a second input electrically connected to a first output of the update device, and an output electrically connected to an input of the core under test. The first input of the first multiplexer is switched to the output when a first control signal is asserted so that the output of the scan device is allowed to directly connect to the output of the first multiplexer to launch a transition by switching the first multiplexer rather than triggering an update event, which is restricted to be triggered in the time of a negative edge.
