USB Device Driver Implementation Under Micro Physiological Parameter Monitor

In the design of portable medical equipment, embedded Linux operation system enjoys great popularization with many advantages such as intelligence、individuality and internet, USB communication , with the advantage of high speed, joint flexibility and etc ,provides a kind of fast、convenient and credible data exchange technique for the equipment and host computer as well as the equipment and function modules. So it’s very important to implement USB device drive under embedded medical equipment based on Linux .This paper the miniature parameter monitor based on embedded Linux,and introduces USB system-structure concept and the development about USB driver in detail.
