Design and realization of USB OHCI driver based on ARM and Linux

MA Yu-tao

Abstract

According to the USB driver skeleton provided by Linux,the paper presented the driver design method of USB OHCI provided by S3c2410 in order to use USB interface among portable electronic devices.This driver realizes the function of USB host and the communication between an USB host and a client device.Developers can make use of USB client devices by enabling the USB host controller support when configuring Linux kernel.The result of driver test experiment proves that USB devices can be used normally on S3c2410.
