Unfortunately there is no native .NET library that offers a solution for this so you should search for some free 3rd party component like SharpUSBLib or LibUsbDotNet. I'm afraid I cannot recommend you any because I didn't use them but I will add that at some point I was trying to create my own handler for USB devices. It's not a easy task to achieve but if interested note that in order to accomplish this you would need to start with a System.IO.Ports.SerialPort .
