摘　　要：设备驱动程序是硬件设备连接到计算机系统的软件接口。Windows驱动程序模型(WDM)是Windows平台的新一代设备驱动程序模型,WDM的研究对设计优良设备驱动程序有重要指导作用。文章分析WDM的工作原理和机制,着重介绍WDM设备驱动程序的设计和实现方法,并给出一个通用串行总线(USB)设备驱动程序的设计实例。该设计将USB驱动程序分为即插即用(PnP)、电源管理、USB初始化和USB设备输入/输出(I/O)等功能模块,具有结构清晰、易移植、复用性好等优点,在USB驱动程序设计中具有良好的应用价值。device drivers are the interfaces that connect devices to the computer. WDM is the latest type of device drivers model based on Windows platform. It is very important to study WDM for writing excellent device drivers. This paper analyzes in depth the working principles and mechanism of WDM, and elaborates its designing and implementation process. It also gives a demo on how to design a USB device driver. The USB driver has been divided into four function modules: plug and play (PnP), power management, USB initialization and USB device I / O, among which USB initialization and USB device I / O are associated with specific USB devices. The method has some merits such as clear structure, easily transportable and effective software reuse. It is also useful for USB driver design in practice.
