Fire HD10 is Not Being Recognized by Calibre 4.3

[John-B]

I have a couple of Fire HD10 tablets that I like to use with Calibre. I recently upgraded to Linux Mint 19.2 Mate edition from Mint 17.3 Mate. I was able to have Calibre 3.46.0 recognize my Fires on Mint 17.3 without problem. My fresh install of Mint 19.2 with Calibre 4.3 does not recognize my Fires even though they are mounted. I also have a Kindle Oasis which is recognized by in my new install.

I have tried rebooting both the Fire and my computer and have tried deleting the driveinfo.calibre and metadata.calibre on the Fire as well.

I really think this is a great program and hope you can help me connect my Fire HD10 by USB.

The Debug device detection returns with my Fire:

On linux only a single program can connect to an MTP device ata time. Prevent your operating system/desktop fro auto mounting the device and it will work fine in calibre.

I have worked on Linux Mint install and got the file viewer to not show the Kindle when it was mounted, but Calibre would still not recognize it. I have switched to using the Calibre Companion which does work for me using the wireless device connection.
