There are some more instructions in
/usr/share/doc/libsane/README.Debian.gz to have the device get the
right permissions when connected.

If I remember correctly: I added scanner to /etc/hotplug/blacklist 
(When I first configure it the scanner module was still there and I had
compiled it with my kernel, it should not be necessary to add it now).
Then in /etc/hotplug/usb/libsane.usermap I added a line for my scanner
like the sample entry provided and replaced VVVV and PPPP by the values
for my Epson 1240U.
Lastly, I commented out the 'usb /dev/usb/scanner0' line I had added to
the /etc/sane.d/epson.conf file and added a new line with simply 'usb'
on it.

YMMV HTH,
