Research On PC To PC Internetworking Through USB Interface

Today, growing of the personal PCs with USB and the devices with USB, all kinds of USB applications fast grow and come to us . we can often see and use various simple USB devices such as USB disks,USB cameras and USB mice in our hands,desktops ,families and in fields of industries,communications and tests ,etc. They enrich and change the people 's lives and work increasingly with silence.On the other hand,with computer popular and informationization process faster it has been very normal that the home has two PCs. Although data transfering and sharing can simply do through two networks'RJ45 intefaces, shares of Internet can't do so because of one network. For realizing it quickly and easily we can link two computers'USB interfaces with a special USB line.Based on this,the paper discusses what USB internetworking's principle is and how to make the internetworking device in practice.First of all, I give in the first and the second chapter a general overview of the USB1.1 protocol and TCP/IP protocol,and make sure of Windows'support for them,and in the third chapter I am based on the system views to part the design into software and hardware, analyse the feasibility of the design and show the solutions of the basical problems about the production,and next chapter I design a externed board in ARM44B0 test board for adding the other USB inteface to form the last test device,and last chapter I describle the program ways and FAQ about software, debug and run.
