I want to write a piece of code in c #, which is need to monitor computer USB interface with external equipment or insert U disk, because they don't quite understand, so want to ask you, the following code I was looking for on the Internet, I'm not so sure function isn't all get on a computer USB interface corresponding ID name, if it is, in the code, please said USB port which is a unique identifier: the DeviceID or PNPDeviceID? If you have any access to judge which one is the interface, if the corresponding state of the interface has a property? Also please the great god, thank you very much


Public class Device
{
String deviceID;
String pnpDeviceID;
A string description;

Public Device (string deviceID, string pnpDeviceID, string description)
{
Enclosing deviceID=deviceID;
Enclosing pnpDeviceID=pnpDeviceID;
This. The description=the description;
}
}

//device USB port information
The static List GetUSBDevice ()
{
List Devices=new List (a);
ManagementObjectCollection collection;
Using (var a searcher=new ManagementObjectSearcher (@ "Select * From Win32_USBHub"))
{
The collection=a searcher. The Get ();
}

The foreach (var device in the collection)
{
Device d=new Device ((string) Device. The GetPropertyValue (" DeviceID "),
(string) device. The GetPropertyValue (" PNPDeviceID "),
(string) device. The GetPropertyValue (" Description "));

Devices. The Add (d);
}

Collection. The Dispose ();
Return devices;
}

Have a look at the solution, and I also can't DingTie

USB connection is a Windows message
Can be received after you override WndProc public const int WM_DEVICECHANGE=0 x219;
