摘要
USB总线是一种快速、双向、同步、低成本、动态可连接的串行总线,其驱动程序是Linux内核的一个重要组成部分.随着在Linux操作系统中的广泛应用,特别是嵌入式设备的大量出现,USB驱动程序的编写越来越显得重要了.分析了USB总线接口驱动程序结构及编写方法,并给出了一个实例.
Universal Serial Bus is a kind of fast, bi-directional, isochronous, low cost, dynamically attachable serial interface bus, and its driver is a main part of Linux kernel. It is used widely in Linux Operating System. Especially with embeded equipment coming out in rush, the design of USB driver is more and more important. In this paper, the architecture and implementation of the USB driver are analyzed with an example given.
