摘　　要：USB是典型的主/从结构.只有USB HOST(主机)才能与USB device通信,其他的设备端口之间不能实现直接通信.本文主要讨论了在嵌入式Linux开发平台下设计USB主机接口设备的一般方法,以及在该平台下USB驱动程序的开发.此外,主机控制器实现了USB总线与计算机系统的连接,本文着重阐述了主机控制器芯片的驱动程序开发.USB is the typical sutmcture of host and device. Every kind of communication is initiated by the host while other devices cannot establish any direct connection to other devices. This paper introduces the development of USB host interface based on Linux system, and the development of USB driver based on it. In addition, USB bus conmmunicates with computer systems by Host controllers. The paper gives detailed information about the desing ideas of Host controllers chip drivers.
