title: How can I detect a USB disconnect event? (Windows, .NET C# application)
body: <p>Currently how I do this is I poll for a masked list of USB devices (masked specifically for the device I'm working with) and if it's there, I continue, if not then I notify the user that the device is not connected.  The method for getting a list of USB devices is provided for me through a USB peripheral controller chip manufacturer's .NET library.</p>
  
  <p>Is there an event somewhere for a USB device disconnect?</p>
