摘　　要：随着USB总线的普及,具有USB主机端和从机端控制器的微型处理器越来越多,AT91RM9200就是这种微型处理器之一。Linux既支持主机端驱动又支持从机端驱动。通过对Linux-2.6.19.2内核USB主机端驱动程序的分析和研究,以及结合U盘设备驱动的实例,讨论基于AT91RM9200的USB主机端Linux驱动,详细地分析Linux内核中USB主机端驱动代码的工作流程,对开发USB设备驱动程序具有一定的指导意义。As USB＇s popularization, there are more and more micro- processors have USB host- side and device- side controller, such as AT91RM9200. Linux kernel supports USB host- side driver and device- side driver. Based on AT91RM9200, this article studies and analyzes USB host - side driver for Linux- 2.6.19.2 kernel and takes USB disk device driver for Linux as an example. The innovating point of the article is that analyzing working flow of USB device driver code for Linux in detail, this is valuable to guiding the other device driver design.
