Example
CopyVB.NET
Imports System Imports System.Windows.Forms Imports LibUsbDotNet.DeviceNotify Namespace Device.Notification Friend Class DeviceNotification Public Shared UsbDeviceNotifier As IDeviceNotifier = DeviceNotifier.OpenDeviceNotifier() Private Shared Sub Main(args As String()) ' Hook the device notifier event AddHandler UsbDeviceNotifier.OnDeviceNotify, AddressOf OnDeviceNotifyEvent ' Exit on and key pressed. Console.Clear() Console.WriteLine() Console.WriteLine("Waiting for system level device events..") Console.Write("[Press any key to exit]") While Not Console.KeyAvailable Application.DoEvents() End While UsbDeviceNotifier.Enabled = False ' Disable the device notifier ' Unhook the device notifier event RemoveHandler UsbDeviceNotifier.OnDeviceNotify, AddressOf OnDeviceNotifyEvent End Sub Private Shared Sub OnDeviceNotifyEvent(sender As Object, e As DeviceNotifyEventArgs) ' A Device system-level event has occured Console.SetCursorPosition(0, Console.CursorTop) Console.WriteLine(e.ToString()) ' Dump the event info to output.
