本文详细介绍了一种在Windows环境下枚举HID设备的方法，包括安装WDK、配置项目属性、使用枚举函数等步骤。通过示例代码展示了如何获取指定供应商ID和产品ID的HID设备信息。

1.先安装WDK

2.项目属性-》VC++目录

包含目录，顺序如下：
   C:/WinDDK/7600.16385.1/inc/ddk
   $(VCInstallDir)include
   $(VCInstallDir)atlmfc/include
   C:/WinDDK/7600.16385.1/inc/api
   $(WindowsSdkDir)/include
   $(FrameworkSDKDir)include

库目录添加 C:/WinDDK/7600.16385.1/lib/win7/i386

可执行目录添加c:\WinDDK\7600.16385.1\bin\x86
