Abstract

This paper analyses stucture and function of the USB driver module,explains the USBD driver stack and divides the USBD driver stack into three software layers,Client Driver layer,USBD layer and HCD layer.Due to there are many researches on development of USBD Client Driver,in this paper,the author expatiates the function of USB OHCI driver and the kernel function of OHCI driver,the function of link list.This gives an allaround technical method to development of the USB driver based on VxWorks.And on the basis of analysis,the author develops the USB HCD based on s3c2510 and VxWorks.
