DF是一种综合的基于XML的文件格式，它结合信息描述标难和信息传输协议，为端到端的工作规范提供了工业标准。

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.

首先是USB系统通讯方法分析，将其归纳为三种主要的形式；然后论述了系统采用的的整体软件架构和通信协议体系，提出了基于嵌入式系统平台的协议栈的基本模型和具体内核实现机制，并阐述了基于此模型的文件传输系统的实现方法；最后，本课题通过综合运用StrongARM处理器上的USB设备控制器和Linux核心中提供的USB设备核心模块与字符设备模块，实现了一套可移植的USB海量存储设备类协议栈，并给出了系统在Widnows和Linux操作系统环境下的测试结果。
