Not needed for scanners any more, I think.

Things are different than they used to be since uscanner(4) is gone.
Now, you can just refer to the USB device, probably ugen2.2 from above.
The Handbook scanning section does have notes for FreeBSD 8.
However, I wanted to create a static device for the scanner at
uscanner0.
First, devd is used to recognize the scanner on attach. devd.conf:
attach 20 {
device-name "ugen[0-9]+";
match "vendor" "0x04b8";
match "product" "0x010a";
action "/bin/ln -sf /dev/$device-name /dev/uscanner0; \
/sbin/devfs rule applyset"
detach 20 {
device-name "ugen[0-9]+";
match "vendor" "0x04b8";
match "product" "0x010a";
action "/bin/rm /dev/uscanner0"
Note that this doesn't care which ugen device is created, it looks for
the vendor and product ID of the scanner. When that device attaches, a
link is created to /dev/uscanner0 and devfs rules are reapplied so the
owner and permissions are set on that link.
Speaking of which, devfs.rules:
add path 'ugen*' mode 0660 group operator
add path 'usb*' mode 0770 group operator
add path 'uscanner*' mode 0660 group operator
About that middle rule: I found that was needed to let non-root members
of the operator group scan. It may be a mistake.
And finally, /usr/local/etc/sane.d/epson.conf has just:
usb /dev/uscanner0
