After testing out the newer version of libmtp v1.1.18, I was able to get
even the current version of Calibre working (as long as I unmounted the
device from Nautilus / GVFS first!)
Here is the initial error if the device is already automounted by GVFS:
Device 0 (VID=1949 and PID=0581) is a Amazon Kindle Fire HD8 Plus.
libusb_claim_interface() reports device is busy, likely in use by GVFS or KDE

To work around Ubuntu's GVFS automount behavior:
- Open Nautilus
- Find your device's product ID name in the mounted filesystems list
- Click the Eject button
- Now open Calibre
After making sure only Calibre is managing the MTP device, it works
fine!
Resolution: Update to libmtp >= 1.1.18
