Create a "USB Viewer" Windows form application. This application will be used to identify and display the currently connected USB devices, including information on what ‘type' of USB device it is.
In addition, you will create a ‘NEW USB' thread, running as a separate thread, to inform you of when a new USB device is connected to, or removed from the System. The system has the ability to notify you when a new USB device has been connected. You must research the necessary System Interface(s) (be it .NET or something else, hint, hint) that will allow you to discover this information on the USBs. You will use your thread to receive the System notification and relay the updated information to the USB Viewer application
