thx提前

解决方案

首先，您必须知道此设备如何向您的代码公开。它是通过COM（串行）端口还是什么？在不知情的情况下，与设备通信是不可能的。



如果有，请参阅设备和/或SDK上的文档。

只需阅读本文，



C＃USB HID接口 [ ^ ]



这应该希望完全帮助您，从这里只是从它获取数据的进展，我相信这将有助于您构建你在USB上的逻辑。



谢谢

thx in advance

解决方案

First, you have to know how this device exposes itself to your code. Is it through a COM (serial) port or what? Without knowing that, it's IMPOSSIBLE to talk to the device.

Consult the documentation on the device and/or the SDK for it, if there is one.

Just read this,

C# USB HID Interface[^]

This should hope fully help you and from here just progress fetching data from it, i am sure this will help you build your logic on USB.

Thanks
