摘要： The present invention provides an improved design of the signal switch, wherein the signal switch comprises at least one combinational logic such as a chip, a plurality of hosts and at least one set of input control device such as a keyboard and a mouse. The chip can further comprise one or more virtual keyboard controller and a plurality of hubs and a multiplexer. The multiplexer of the present invention is utilized to detect and interpret signals. The present invention utilizes the combinational logic design of the chips and the multiplexer to provide a signal switch that can share multi-upstream devices but less downstream ports, only one set of keyboard and mouse is required. Multiplexing downstream devices among multiple hubs, which are dedicated to upstream hosts, help reducing the whole enumeration process of time. The signal switch of the present invention provides an improved design by replacing the central processing units (CPU) of a conventional design of signal switch with the combinational logics such as chips in order to increase the speed of the enumeration, as a result, the enumerating time is thus reduced.

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

摘要： A universal serial bus (USB) apparatus for lowering power consumption is provided. The universal serial bus apparatus includes a universal serial bus circuitry, a monitor unit, and a system duty clock generator. The monitor unit is used to monitor a start of frame (SOF) packet generated by the universal serial bus circuitry and generates a clock control signal accordingly. The system duty clock generator receives the clock control signal and a reference clock signal to generate a system duty clock signal. The enable or disable status of the system duty clock signal can be determined according to the SOF packet monitored by the monitor unit so as to make the universal serial bus apparatus enter into runtime idle mode to lower the power consumption.
