摘要： A USB peripheral device with dynamic modification class is connected to a basic system of processor through a USB transmission interface. 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 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.
