DriverStudio was used to develop WDM driver for PL2303 chip; and both WDM driver and USB communication protocol were introduced, including operation steps and DriverStudio installation. Taking PL2303 chip as the object of study and completing relevant code writing on the experimental hoard show that operating time of the development board can be shorted significantly along with a well-improved communication efficiency.%使用DriverStudio开发工具为PL2303芯片开发了一套WDM型驱动程序.介绍了WDM驱动程序概念、USB设备通信协议,阐述了DriverStudio开发工具的操作步骤和驱动程序的安装.在自制的学生实验开发板的基础上以PL2303芯片为对象进行了WDM型驱动程序的开发研究,并完成相关代码的编写,得到了实验的验证.结果表明:可以明显地简化开发板的操作时间并且提高了通信效率.
