摘　　要：目前大量专用型低速USB设备仅能在特定操作系统或软件环境中识别和使用,给实际工作带来很大限制。首先简单分析低速USB设备的性能特点及通讯原理,在此基础上设计出一个低速USB设备通讯模块,并在Tangent Devices的Wave控制台上进行编程实验。实验结果证明模块能够较好地实现专用型低速USB设备在不同操作系统和软件环境下的双向通讯。Many special low-speed USB devices can only be identified and used in a specific operating system or software environment, which may cause some difficulties for practical work. Introduces the characteristics and communication mechanism of low-speed USB devices, based on it, designs a module for low-speed USB devices, and programs on Tangent Wave Console. Results show that the module can better achieve the two-way communication function of special low-speed USB devices in different operating systems and software environments.
