如何确定USB端口是否可用? [英] How to determine USB Port is available for use or not?

问题描述

我正在开发C#应用程序，该应用程序需要查找是否可以免费使用任何USB端口.

I am developing C# application which needs to find any USB port is free for use or not.

是否有任何C#类或WMI查询来确定USB端口是否免费使用?

Is there any C# class or WMI query to determine USB Port is free for use or not?

假设，
如果计算机上有5个USB端口，而其中2个已经被鼠标占用，则键盘
其余3个是免费的.
因此，我需要确定这些未使用的端口.

Suppose,
If a machine has 5 USB ports and out of which 2 are already occupied by mouse ,keyboard
and remaining 3 are free.
So I need to identify these ports which are not in use.
