  I have used the following code to detect usb insertion.

  private void CreateUSBEventHandler()
  {
  WqlEventQuery q;
  ManagementOperationObserver observer = new ManagementOperationObserver();
  // Bind to local machine
  ManagementScope scope = new ManagementScope("root\\CIMV2");
  scope.Options.EnablePrivileges = true; //sets required privilege
  try
  {
   q = new WqlEventQuery();
  q.EventClassName = "__InstanceCreationEvent";
  q.WithinInterval = new TimeSpan(0, 0, 3);
  q.Condition = @"TargetInstance ISA 'Win32_USBControllerDevice'";
  Console.WriteLine(q.QueryString);
  m_ManagementEventWatcher = new ManagementEventWatcher(scope, q);
  m_ManagementEventWatcher.EventArrived += new EventArrivedEventHandler(this.UsbCreationEventArrived);
  m_ManagementEventWatcher.Start();
  }

  catch (Exception ex)

  {

  Console.WriteLine(ex.Message);

  DestroyUSBEventHandler();

  }

  The problem is that I insert one device and my handler gets called four times. Why would that be? Is there a way to determine what kind of device or manufacturer of device was plugged in? I am only looking to monitor certain devices.
