摘　　要：通用串行总线（ＵＳＢ）是一种正在迅速发展的高速外设总线，它具有热插拔、智能化、易于使用等特点．本文介绍几种正在迅速发展的外设总线，然后讨论了ＵＳＢ技术的原理及其工作流程和实现技术．This paper presents USB ,standing for Universal Serial Bus(USB), an emerging external bus employed in connecting peripherals with PC. The principle and implementing method of this bus are introduced. The virtue of USB comes from its ability of being shared in essence. In USB system, the devices can be attached and detached without the need of turning off power supply. It is intelligent and expansive as well as reducing the complexity of development of new peripherals.
