title: How to uniquely identify devices connected to com ports in a prolific USB to Serial hub?
body: <p>I have a Joystick connected to USB to Serial Com port hub. In device manager it shows 4 listings,</p>
  
  <blockquote>
  <pre><code>Prolific USB-to-Serial Comm Port(COM21) 
  Prolific USB-to-Serial Comm Port(COM22) 
  Prolific USB-to-Serial Comm Port(COM23) 
  Prolific USB-to-Serial Comm Port(COM24)
  </code></pre>
  </blockquote>
  
  <p>The machine is at remote location, so I couldn't check physically which port it is connected. So using remote desktop, is there any way to identify the COM port that Joystick is connected to?</p>
