I went to the handbook first before sending this email and before madly
surfing the web. If you look at my epson.conf file:
# grep -v "^#" /usr/local/etc/sane.d/epson.conf
usb 0x04b8 0x011e
usb /dev/uscanner0
The second line is pointless as with Freebsd 8.X there is no /dev/uscanner
of any kind. The first line indicates that there's a usb scanner of
product id: 0x04b8 and Vendor id: 0x011e as indicated in the file in
question.
...
That is why when I issue the command:
# scanimage -d epson --format=tiff > foo.tiff
it actually works. Yet it's in low resolution and so forth. Yet if
I issue the command:
# scanimage -L
No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).
Which is quite annoying.
Okay, the other thing to check is permissions to the USB devices. From
devfs.rules:
add path 'ugen*' mode 0660 group operator
add path 'usb/*' mode 0660 group operator
With that, and the USB IDs in epson.conf, my Epson 1640SU works fine
with a normal user:
% scanimage -L
device `epson2:libusb:/dev/usb:/dev/ugen2.3' is a Epson Perfection1640
flatbed scanner
