USB(即Universal Serial Bus)是一种通用串行总线。随着技术水平的提高，计算机的广泛应用，人们对串行通信提出了更高的要求。开发一种兼容低速和高速的技术，从而为广大用户提供一种可共享的。可扩容的。使用方便的串行总线成为众多厂商的共同目标。为了实现整个计算机系统中总线的一致性，USB已发布了一种成为通用计算机串行技术规范，简称为USB。-USB (or Universal Serial Bus) is a Universal Serial Bus. With the skill levels improve, the wider use of computers, serial communication of a higher demand. The development of a compatible low-speed and high-speed technology, so as to provide a vast number of users can be shared. May be the expansion. Easy-to-use Serial Bus has become the common goal of many manufacturers. In order to realize the entire computer system bus consistency, USB has released a general-purpose computer serial become technical specifications, referred to as USB.
