title: Use canon or third party digital camera in unity for ar-camera options
body: <p>I want to use canon or third party digital camera in unity for AR-camera options.
  The only option available in "Camera Device" drop down is "USB Camera".<br>
  How can I get my device to appear in that list (External Canon Digital Camera)?
  Refer attached image . 
  I have connected canon EOS Camera but it is not displayed in the Camera Device drop down.
  Please help me.</p>
