I have all the emul-linux packages installed except for java, medialibs and 
sdl. I can't imagine that any of those is causing this problem.

In answer to Barry, I have this:

$ cat /etc/udev/rules.d/92-scanner.rules
BUS=="usb", SYSFS{idVendor}=="0x4b8", SYSFS{idProduct}=="0x106", 
GROUP="scanner", MODE="660"

Those numbers are I believe correct for my scanner.

In reply to Antoine, after removing all other entries 
from /etc/sane.d/epson.conf I get these log entries when I plug the scanner 
in:

So the scanner evidently is being detected and recognised, but I still get 
no-scanners from scanimage -L.

Maybe the scanner is faulty, but it does work for M$.
