请教一下，关于 Windows 上捕获特定设备的按键事件以及如何区分设备，应该怎么做？

Hi。

最近在做一个简单的小东西。需要一个类似遥控器的东西来控制（只需要一个按钮就够了）。没有看到合适的设备就买了一个 ppt 翻页笔，这个东西原理上是一个键盘设备（系统硬件中能查到）。但是按键都是上下左右回车 esc 这种很常用的按键，直接挂全局 hook 太影响日常使用了，所以想请问下有没有什么方法可以挂特定设备的键盘事件吗？

我现在做了一半的尝试是用 windows 的 Raw Input API。还不确定能不能绑定（文档看起来似乎可以），不过查了基本的设备信息之后发现几乎很难从键盘设备中确定哪个才是 USB 无线翻页笔。所以还想问一下有没有 dalao 对这个有什么思路的？

提供一下我现在的 raw input 的设备信息：(拔了再插之后能确定第一个应该是 USB 翻页笔）

通过注册表查第一个设备的注册信息是这样的：（跟普通键盘似乎没太大差别，不知道应该如何区分出来）

（实际上。。哪怕只区分设备来自 usb 我也很知足了。。）
