随着USB技术日趋成熟，USB开发者只需要关注顶层开发即可，这样虽然减少了工作量，但容易使开发者忽略USB基础理论与概念，导致的弊端在于开发者一旦遇到问题，往往不知如何解决。作者基于多年USB开发经验。针对当前很多USB开发者容易混淆的概念，进行深入浅出的剖析，针对枚举和重枚举的区别、不同启动方式的区别等问题，进行了归纳总结。本文从对比的角度分析问题，有助于开发者理清USB的工作机理。

As the technology of USB matures, USB developers just need to pay attention to top development, which reduces a lot of their work. However, it will make developers neglect the basic principle and concepts of USB communication, then lead to some problems hard to solve. With rich experience about USB development, author of this article analyses some concepts confusing for most of developers, summarizing the difference between enumeration and re-enumeration and the distinction among various ways to start USB communication. Analyzing problems by means of comparison, this article will help developers understand the mechanism of USB.
