嵌入式Linux系统下的USB驱动程序开发

Development of USB Driver Based on Embedded Linux System

嵌入式Linux系统的应用越来越广泛,功能也越来越强大,速度也越来越快。对于在计算机中常见到的USB设备来说,在Linux系统中USB驱动开发是非常有必要的,同时Linux内核对USB设备的支持也非常完善。本文从USB驱动开发的实例出发,介绍了USB设备驱动的基本架构,以及驱动开发过程中的关键技术。

The applications of Embedded Linux system aremore and more widely, itsfunctions are also more and more powerful, and its speed is also more and more faster.For USB devices often used in a computer, the USB driver development is necessary in the Linux system,at the same time, the Linux kernel support for USB devices is also very perfeet. this paper basedon the practical example of the USB driver development, describes the basic framework of the USB device driver, and the key technology in the process of driver development.
