Linux下USB设备驱动研究与开发

Research and Development of USB Device Drivers in Linux

本研究旨在开发一款支持智能设备与主机之间通过USB通信的读写控制程序,并保证数据的正确和稳定传输,采用了基于CyAPI库的USB驱动程序开发方法。在本研究中,首先选择了适当的工具和芯片,确保它们与Linux操作系统兼容并能满足项目要求,设计了驱动程序和传输控制程序的方案,并详细描述了它们的功能和实现思路。通过调用设备驱动程序,能够直接控制USB设备并实现数据传输,同时及时正确地收到智能设备的信息反馈。

This research aims to develop a read and write control program that supports USB communic-ation between smart devices and hosts,and ensures correct and stable data transmission.The USB driver development method based on the CyAPI library is adopted.In this study,appropriate tools and chips were first selected to ensure compatibility with the Linux operating system and meet project requirements.The driver and transmission control program schemes were designed,and their functions and implementation ideas were described in detail.By calling device drivers,it is possible to directly control USB devices and achieve data transmission,while receiving timely and accurate feedback from intelligent devices.
