I'm affected as well, my scanner is an Epson GT-S50 (0x04b8 0x0137).
I've documented my observations and trials to resolve on askubuntu.com:
https://askubuntu.com/questions/1034528/epson-gt-s50-scanner-not-
working-after-upgrade-to-18-04-from-16-04
I tried also to do a fresh install of Bionic, but same issue.
I tried to specify my scanner in /etc/sane.d/epkowa.conf (I've added
"usb 0x04b8 0x0137" -without the double quotes- in the appropriate
section of the file) and added the following UDEV rules in a
55-libsane.rules file under /etc/udev/rules.d/
> SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", MODE=="0666"
SUBSYSTEM=="usb_device", MODE=="0666"
ATTRS{idVendor}=="04b8", ATTRS{idProduct}=="0137", MODE="0666",
GROUP="scanner", ENV{libsane_matched}="yes"
So far, no luck, scanner remains stubbornly undetected :'(

Title:
Many 3rd party scanner drivers are broken by a sane change
Status in sane-backends package in Ubuntu:
Confirmed
Bug description:
Many scanners can no more be used since sane has changed something:
The 3rd-party plug-in the vendor provides as .deb package will still
install. But the scanner is no more recognized.
Scanners that are affected are(besides others):
- Epson Perfection V10
- Epson Perfection V1000
- Epson WorkForce GT-1500
- Brother MFC-8510DN
- Epson Perfection V33
It is to note that the probability that the scanner manufacturers fix
things others broke is below 100%.
