First, we analyse USB communication methods, and there are three important methods; Second, we discuss the whole software structure and communication protocols and design a basic protocol model based on embedded environment. Then, we explain the implementation of a file transport system based on this model. Through the comprehensive utilization of StrongARM UDC and Linux USB modules, we complete a portable protocol stack. Moreover, the function of the system is tested under the Windows and Linux OS.This thesis provides us with a full description on the realization of the USB mass storage system.
