Usb.Events

Subscribe to the Inserted and Removed events to be notified when a USB drive is plugged in or unplugged, or when a USB device is connected or disconnected. Usb.Events is a .NET Standard 2.0 library and uses WMI on Windows, libudev on Linux and IOKit on macOS.

How to use:

1. Include NuGet package from https://www.nuget.org/packages/Usb.Events

    <PackageReference Include="Usb.Events" Version="1.1.0.1" />
   

2. Subscribe to events:

    using Usb.Events;
   
    class Program
    {
        static readonly IUsbEventWatcher usbEventWatcher = new UsbEventWatcher();
   
        static void Main(string[] _)
        {
            usbEventWatcher.UsbDeviceRemoved += (_, device) => Console.WriteLine("Removed:" + Environment.NewLine + device + Environment.NewLine);
   
            usbEventWatcher.UsbDeviceAdded += (_, device) => Console.WriteLine("Added:" + Environment.NewLine + device + Environment.NewLine);
   
            usbEventWatcher.UsbDriveEjected += (_, path) => Console.WriteLine("Ejected:" + Environment.NewLine + path + Environment.NewLine);
   
            usbEventWatcher.UsbDriveMounted += (_, path) =>
            {
                Console.WriteLine("Mounted:" + Environment.NewLine + path + Environment.NewLine);
   
                foreach (string entry in Directory.GetFileSystemEntries(path))
                    Console.WriteLine(entry);
   
                Console.WriteLine();
            };
   
            Console.ReadLine();
        }
    }
