[digiKam-users] How to interpret DigiKam error message when connecting to camera

a squared
I'm new to Digikam. I'm trying to ingest images into DK under linux Mint 19.3 from my USB connected Fujifilm X-T20. The camera is correctly identified by DK, but an error message says DK cannot connect to the camera and asks me to make sure the camera is connected properly and switched on. I believe that both of these requirements are met because other apps. (XnView, Rapid Photo Downloader, Mint file explorer) can read the camera SD card. The error message is misleading, possibly wrong. How do I make DigiKam present the real problem it is having, so that I can ingest images from the camera?

Under windows, on another computer, DK is unable to detect the camera and I don't understand the settings to be entered to manually identify the camera to DK. How to I set these parameters?

It's possible that the camera only connects to your computer as MTP or PTP
device. Iirc, that means that only one application at a time can have access
to it. And if your system auto-mounts the camera, that means it has grabbed
that access.

Personally, I prefer using an external card reader to download images. Such a
card reader is recognised as a USB mass storage device (aka disk drive), and
that works very well.

No idea, like I said above, I use a separate card reader. However, Digikam
uses gphoto2 for PTP/MTP transfers. That said, according to their
documentation, gPhoto2 supports your camera..

But perhaps you can set the camera to appear as a mass storage device?
