推荐答案

我知道这是不是你想要听到的，但有没有全包的方式做你想做的。

I know this isn't what you want to hear, but there is no all-inclusive way to do what you want.

个别品牌和型号都有自己暴露它的方式。例如，我已经做了突触触摸板（很常见），它暴露在Windows COM接口的一些工作。该代码将无法在任何其他触摸板工作。

Individual makes and models have their own way of exposing it. For example, I've done some work with Synaptic touchpads (fairly common) which expose a COM interface on Windows. That code won't work on any other touchpads.

您可以根据哪些系统支持多找几个常见的并运行不同的代码。

You could find a few common ones and run different code based on which ones the system supports.
