title: Mysterious error message "The port 'COM1' does not exist"
body: <p>I am getting the following error message when trying to access devices connected by USB port.</p>
  
  <blockquote>
    <p>The port 'COM1' does not exist</p>
  </blockquote>
  
  <p>By looking into device manager, I am certain that the device has been assigned COM1 and no other device is attached to COM1. Why would this behavior occur?</p>
  
  <p>Is this environment dependent, because the same version of the App doesn't produce this message when executed in a different system.</p>
