摘　　要：结合基于USB总线的数据采集设备,介绍了WDM驱动程序的工作原理,设计原则和设计方法,并给出一个实现块传输的USB设备驱动程序例程,详细的介绍了该例程的各个功能模块。该例程性能稳定,传输可靠,已应用于数据采集设备中。对系统的性能进行测试的结果表明:数据的传输过程达到了设计的要求。驱动程序设计过程的详细介绍对USB专用设备驱动程序的设计和开发具有良好的参考应用价值。Combine to the data acquisition device based on USB bus, It introduced operational principle, design principle and design method of WDM driver. It also gave a driver routine for implementing USB bulk transfer, Introduced the routine＇s every functional module. It has stable function, reliable transmission. It has already been applied to data acqui- sition device. The testing results of the system function has been proved that the data transmission procedure coming to the design request. The detailed instruction for the design procedure of the driver program is useful for design of special USB device driver in practice.
