Abstract
As the accelerated adoption of Universal Serial Bus(USB),USB,especially USB host,has become an important technique in an embedded system.Because of the complexities of USB host software,the implementation of USB system software,which is also the core of USB host,will play an important part in an USB communication system.This paper gives an analysis of USB BUS system and HW/SW structures of USB host firstly,and then,presents a description of implementation of USB host stack and USB system software based on ASIX-OS RTOS and a detail application which provides the applicable environment and its performance.
