WinUsbDeviceWatcher Class

• Provider Usb Insert/Remove Events.
• Include Usb device information such as PID, VID and Path etc.

namespace Walle.WinUsb.Sample
{
    internal class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("WinUsbDeviceWatcher Sample:");

            WinUsbDeviceWatcher watcher = new WinUsbDeviceWatcher();
            watcher.DeviceConnectEventHandler += Watcher_DeviceConnectEventHandler;
            watcher.DeviceDisconnectEventHandler += Watcher_DeviceDisconnectEventHandler;
        }

        private static void Watcher_DeviceDisconnectEventHandler(object sender, WinUsbDeviceEventArgs e)
        {
            Console.WriteLine("Detected Usb Device Event: {event} Path:{path},VID:{vid},PID:{pid}", e.EventType, e.Path, e.Vid, e.Vid);
        }

        private static void Watcher_DeviceConnectEventHandler(object sender, WinUsbDeviceEventArgs e)
        {
            Console.WriteLine("Detected Usb Device Event: {event}, Path:{path},VID:{vid},PID:{pid}", e.EventType, e.Path, e.Vid, e.Vid);
        }
    }
}

WinUsbDevice Class

• Get the inserted USB device list.

namespace Walle.WinUsb.Sample
{
    internal class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("WinUsbDevice Sample:");

            var pathes = WinUsbDevice.GetAll();
            foreach (var path in pathes)
            {
                Console.WriteLine($"{path}");
            }
            Console.ReadLine();

        }
    }
}

WinUsbDevice.GetAll() Result:

\\?\usb#vid_0a12&pid_0001#5&2f03355&0&6#{a5dcbf10-6530-11d2-901f-00c04fb951ed}
