Gave it another test under Mint 20.0, still sees something else as locking the device. I mentioned it might be Gnome3-specific because I use Cinnamon, not Gnome. It does recognize the phone (sees a Moto E5 as a Moto G, but I expect the internals are pretty much the same).
Won't work on my system, I can only presume it's the "usb_storage" module, as none of the modules it suggests as preventing gphoto2 from claiming the device are running.
Needs further investigation, or it's somehow Gnome3-dependent.
