This is wrong! The major device number 180 is used for the whole
USB subsystem, and not just for the scanner.
Edit the file dll.conf and make sure that the "epson" entry is configured.
If you want to make sure that the v4l backend is no longer reported, you
can comment out all other entries in this file.

If this still does not help, please create a log file and email this
to me:

export SANE_DEBUG_EPSON=128
scanimage > /tmp/scan.log 2>&1
