The user access ACL entry is missing. That explains why your ordinary
user cannot access the device. (I assume that udev and systemd work fine
on your machine, or have you noticed issues that might be relevant?)

That won't survive a reboot, and when removing+readding the device the
problem would reappear.

Do you run with SELinux enabled and enforcing?
Do you get denials in /var/log/audit/audit.log? (it could be that XFCE
doesn't run the SELinux troubleshooter, so you would not learn about
SELinux problems)
What happens if you switch to "permissive mode" temporarily (either
at boot time) or by running "setenforce 0" as root, then plug in the
scanner?
