Can you please run these commands to create a log file:

export SANE_DEBUG_EPSON=3D128
scanimage -d epson:/dev/sg0 --preview yes > /tmp/scan.log 2>&1

This will write all commands and data that is exchanged between
the scanner and the backend to the file /tmp/scan.log

Please attach this file to an email and send it to me.

Thanks,=20

Karl Heinz
