问题描述

我尝试检索连接的USB设备的PID和VID。从这行C#代码开始:

I am trying to retrieve PID and VID of a connected USB device. Starting with this line of C# code:

System.Management.ManagementClass USBClass = new ManagementClass("Win32_USBDevice");

然后我得到异常ManagementException not found,后来我遇到这个链接:

Then I got exception "ManagementException not found", Later I run into this link:http://msdn.microsoft.com/en-us/library/windows/desktop/aa394084(v=vs.85).aspx

原来 Win32_USBDevice 根本不在列表中。尝试 Win32_USBController 但没有得到我想要的。任何人都可以让我知道列表中是否有任何替代类来提取连接的USB设备的PID和VID?

It turned out Win32_USBDevice was not on the list at all. Tried Win32_USBController but didn't get what I wanted. Could anyone let me know if there is any substitute class on the list to extract PID and VID of a connected USB device?

提前感谢!

推荐答案

System.Management.ManagementClass USBClass = new ManagementClass(Win32_USBHub);
