In this paper, the advantages of Universal Serial Bus (USB) over the traditional ether net are described. The transmitting type as well as the bus data management and its features during the course of transmitting are briefly introduced. As far as the practical application is concerned, the relationship between USB and serial port is discussed in the paper, and the design of the transition from USB to serial port and the one from serial port to USB are brought out, whose maneuverability is to be testified through experiments.
