Universal Serial Bus In The Remote Data Communications Applications

Universal Serial Bus is new technology about interface in computer application. USB has been used widely since the Windows operation system supported the USB interface in computer. The major goal of USB was to define an external expansion bus which makes adding peripherals to a PC as easy as hooking up a telephone to a wall-jack. The program' s driving goals were ease-of-use and low cost. These were enabled with an external expansion architecture.This paper mainly introduces the work principle and the communication protocol of USB. A Comprehensive Rmote Data Communication System is designed based on USB. Then describes how to develop the software of USB under Windows platform.
