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?
Doesn't make sense, I have to be logged in in order to start gimp and choose what xsane device to use.
Sense #1: a) Connect scanner b) Log in c) Start gimp ...
Sense #2: a) Log in b) Connect scanner c) Start gimp ...
Any difference?
Hum.
It can be weeks till I next log out.
I can try with another user.
But I don't think it will make any difference. The scanner is always detected, that's not the problem. The problem is when actually trying to scan, that version 2 of the library fails.
Ok, I tried with a second user, without login out from the first, the scanner connected. The scanner was detected fine, and epson2 failed with the same error when attempting to scan.
Just had to reboot, accidentally. Scanner was powered and connected since boot. Made no difference. -- Cheers / Saludos, Carlos E. R. (from 15.4 x86_64 at Telcontar)
