USB编程研究之二（常见设备类型的GUID)

在USB编程之前要事先了解一下GUID的概念。

应用其他网页中的定义：

    全球唯一标识符 (GUID) 是一个字母数字标识符，用于指示产品的唯一性安装。在许多流行软件应用程序（例如 Web 浏览器和媒体播放器）中，都使用 GUID。
    GUID 的格式为“xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx”，其中每个 x 是 0-9 或 a-f 范围内的一个十六进制的数字。例如：6F9619FF-8B86-D011-B42D-00C04FC964FF 即为有效的 GUID 值。
    在计算机领域有很多东西需要不重复的唯一标识的东西，例如设备的类型，类，接口标识，目录名等等。这是个天文数字，我记得是有工具能自动生成这个GUID码的，反正不同地点，不同时间，生成相同的GUID的可能性很小很小很小，小到什么程度，没查过，基本上可以认为是不可能生成相同的GUID值的。

 

计算机中有各种个样的设备类型，这些设备类型被微软用固定的GUID来标识了，这些GUID对实际编程是有很大关系的，用错了会麻烦，我查了一下文档，把查到的设备类型的GUID列在下面供大家参考：
