摘   要
USB是英文Universal Serial Bus的缩写，中文含义是“通用串行总线”。它是一种应用在PC领域的新型接口技术。早在1995年，就已经有PC机带有USB接口了，但由于缺乏软件及硬件设备的支持，这些PC机的USB接口都闲置未用。1998年后，随着微软在Windows 98中内置了对USB接口的支持模块，加上USB设备的日渐增多，USB接口才逐步走进了实用阶段。
这几年，随着大量支持USB的个人电脑的普及，USB逐步成为PC机的标准接口已经是大势所趋。在主机(host)端，最新推出的PC机几乎100%支持USB；而在外设(device)端，使用USB接口的设备也与日俱增，例如数码相机、扫描仪、游戏杆、磁带和软驱、图像设备、打印机、键盘、鼠标等等

Abstract
English USB Universal Serial Bus acronym, Chinese meaning is 'Universal Serial Bus.' It is a PC application in the field of new interface technologies. As early as 1995, there was already a PC with a USB interface. However, the lack of software and hardware support, PC USB interface were inactive. After 1998, with the Microsoft Windows 98 built-in USB interface for the support module, USB devices with the increasing number of USB gradually entered the practical stage. In recent years, with substantial support USB PC penetration. USB PC gradually become the standard interface is the general trend. The host (host) side, the newly introduced PC - almost 100% support Apple In Peripherals (device) end, the use of USB interface equipment is growing, such as digital cameras, scanners, joysticks, tapes and floppy
