Description: 通用串行总线（USB）具有方便快速一系列优点，近年来已经发展成为一种比较普遍的计算机与外设的接口。在设计USB设备的过程中不可避免的要涉及到设备驱动程序的设计。首先整体上简要介绍了USB及其通信模型，然后详细讨论了Windows的WDM驱动程序模型,重点阐述了基于WDM的USB设备驱动程序的具体开发过程。最后给出了当前流行的几种USB设备驱动的开发工具及其特点。通过设计USB设备驱动，实现了自行设计的USB数据采集系统与PC的通信。
关键字：通用串行总线（USB）； USB请求包(URB)；即插即用（PnP）；USB设备驱动程序-For USB’s the advantages of convenience and higher speed, recently it has become a popular interface between computer and peripheral device. It is inevitable to design USB Device Driver when we design a USB system. Firstly, the paper singly introduces the whole structure of a USB system, then describes Windows Driver Model (WDM) in detail, emphasis elaborates how to develop a USB Device Driver based on WDM. Finally, gives several popular tools and its characters to develop USB Device Driver. By designing USB Device Driver, we implements communication between our USB data acquisition system and PC.
