推荐答案

您提到了USB 2.0接口，因此在大多数情况下，您将需要使用制造商提供的类似API的东西.最快的方法是向您的护照卡扫描仪供应商索要开发套件.如果这不可能，那么您可以尝试在互联网上查找该特定型号，并希望该SDK可用.

您所需的此文件通常是扩展名为.dll的文件，并且可能需要使用VB.NET互操作类来使用它(就像使用Windows API(例如FindWindow，WriteProfileString等)一样.寻找您的API，然后我们可以从那里开始.

You mentioned USB 2.0 interface so in this case most of the time you will need to use something like an API that is provided by the manufacturer. The quickest way would be asking your passport card scanner supplier for the Development Kit. If that is not possible then you could try looking on the internet for that particular model and hopefully the SDK is available.

This file that you need is usually a file with .dll extension and you probably need to use VB.NET interop classes to use it (just like using windows API like FindWindow, WriteProfileString, etc). Look for your API and then we can start from there.
