Windows设备的一种管理方式就是在安装设备驱动的时候，通过INF文件中的Class和ClassGUID来设置,如
Class=USB
ClassGuid={36FC9E60-C465-11CF-8056-444553540000}
当设备驱动安装后，可以通过SetupDiClassNameFromGuidEx和SetupDiClassGuidsFromNameEx函数在Class名和ClassGUID之间进行转换。
当然我们也可以使用SetupDiGetClassDescriptionEx函数获取类的描述符信息。
#define LINE_LEN 256
TCHAR classDesc[LINE_LEN];
if(!SetupDiGetClassDescriptionEx(&guids[index],classDesc,LINE_LEN,NULL,Machine,NULL))
{
if (FAILED(StringCchCopy(classDesc,LINE_LEN,className)))
{
goto final;
}
}
当然我们也可以通过DevCon来显示系统中所有的设备类,命令行为:
devcon.exe classes
