My camera with UMS was treated as removable medium for years and readily showed up in device notifier when plugged into USB. But suddenly that changed: The camera does no longer show up as removable medium, but is now listed as nonremovable and requires root permission to mount.
When removing the SD card from the camera and inserting it into a USB card reader everything works normal. Device Notifier pops up and mounts the card with user permissions. I am puzzled. Any idea?
That does read like a regression… perhaps with udev?
What is reported when the device is plugged in and you then mount it
udisksctl monitor
dmesg --follow
Let’s see how the device is flagged as removable or not
udevadm info -a -n /dev/sdb1|grep removable

Strange… from a udev perspective the attributes show that it is a removable device (as expected). Is your camera the only mass storage device behaving like this? Try with a USB stick if you have one at hand. I can’t replicate this unfortunately.
Check your removable media settings (although I don’t think the issue is dues to this)
System Settings (systemsettings5) > Removable Media
Removable Media has every box unchecked. Inserting an USB stick pops up the device notifier as expected!
Okay, so other devices work as expected. Going back to the camera, what happens if you connect and try to mount it with udisksctl (as regular user)?
udisksctl mount -b /dev/sdc
When trying to connect I inadvertently dropped the camera on the carpet floor. Upon connecting device notifier popped up. Retried connecting several times successfully. Seems to be a hardware glitch.
That’s one way of fixing it. 
I did note that it was being mounted read-only before
10:35:54.176: /org/freedesktop/UDisks2/jobs/35: org.freedesktop.UDisks2.Job::Completed (true, 'mount: /dev/sdc1 is write-protected, mounting read-only
')
Was that due to the write protect tab on the SD card perhaps? Although that should have caused problems for you taking photos.
Definitely no.
What I found: Attaching the Camera with the SD card removed causes the problem. In this case the internal memory is mounted. When unmounting, unpluging the camera, inserting the SD card and plugging in again, device notifier fails to detect the camera as removable device, but shows it as nonremovable.
I then blocked /dev/sdc with an USB stick. Plugging in the camera results in device notifier detecting the camera at /dev/sdd and readily mounting it without requesting authorization. Thus I think there is a bug somewhere in openSUSE.

My first foreman always said “don’t force it get a bigger hammer”. LOL

That is an unusual find. If you can replicate that, consider submitting a bug report.
That doesn’t stop the temptation when things aren’t going right.
Needed to reboot the machine for reverting to business as usual, which is PITA. Tried restarting systemd-udevd to no avail. Will restarting udisks2 preserve the user sessions?
Sorry, what was the reboot needed for?
Is the following not sufficient?
udevadm control --reload-rules
To restart UDisks2 do
systemctl restart udisks2
After taking some photos on Sunday I successfully downloaded them using digiKam. Then I unmounted the camera, unplugged it, pressed power off, removed the SD card, pressed power on and plugged it again. Device Notifier readily mounted internal memory of the camera.
Then I reverted to inserting the SD card and tried again. Now the symptoms were different from the first trial. Device Notifier showed the SD card as external drive, but repeating mount/umount ended up in killing the plasma shell. I was left with an entirely dark screen and a mouse cursor moving on the screen.
What is reproducible: Mounting the camera with the SD card removed and remounting it with the card in place again causes things to become shaky and in the end I needed to kill the user session and start again.
Thanks for clarifying. That’s worthy of a bug report IMO.
