I had a bug that have been nagging me for a few years, for forgetting to report.
I plugged my Epson scanner (Perfection 1650):

I opened up gimp, selected File, Create Xsane device dialog. Then I would select the first entry in the photo, using epson2 library:
https://paste.opensuse.org/pastes/d884de97a177
An one day, suddenly, that library failed, and I had to select the "epson" library instead. That could be Leap 15.2 or 15.3. So, today, as I was going to scan some papers I remembered and decided to report, so started to take notes as I prepared the scanner.
And today it works! Heisenbug? :-o
Does it make any difference whether you connect/power-on the scanner before vs. after logging in to your DE? Check with 'scanimage -L', too. (searches for devices) -- Robert Webb
