Calibre not detecting my Kindle Fire device

Calibre Version 3.9

I followed the advice from the link provided about my topic and none of it helped unfortunately. I got a device report though.

Devices possibly connected: None

As you can see the device is detected by Calibre but isnt showing up as a connected device within the program itself. Is there something I'm missing here?

On linux only one program at a time can open MTP devices. Prevent your
desktop from auto mounting the device and it will work in calibre.
