摘　　要：　通用串行总线〔USB〕是一种新型的计算机外围接口标准.它具有即插即用、扩展方便、数据传输率高等特点.但由于USB总线协议复杂,使得USB设备的开发比较困难.本文首先介绍了USB的总体性能及特点,然后对USB总线的系统体系结构、通信模型、机械规范和电气规范以及USB设备结构作了简要介绍,总结了USB设备开发的一般过程,并对目前USB芯片进行了简要介绍.USB(Universal Serial Bus) is an up-to-date interface standard of computer peripherals, with some advanced features such as PnP(Plug and Play), easy extensibility and high data rate. USB protocols are very complicated, which make it very difficult to develop USB devices. This paper first presents generic performance and characteristics of USB, then gives a brief introduction to systematic architecture, communication model, mechanical procedures, electrical properties and device structures of USB, and summarizes a general process to develop USB devices. USB chips are also briefly related.
