In contrast to what many other people might suggest, I'm personally not
a big fan of providing users broad access to all kinds of device nodes.
So instead of messing around with permissions, I prefer to make use of
the saned(8) network daemon.
This is actually pretty straightforward to set up. You'll need to add
these two lines to your /etc/rc.conf:
saned_enable="YES"
saned_uid="root"
Now either reboot the machine or run the following command to start
the network daemon right away:
# service saned start
Then add the following line to /usr/local/etc/sane.d/net.conf:
localhost
Any non-privileged user should now be able to access the scanner.
For starters, try to get a list of scanners available on the server:
> scanimage -L
device `net:localhost:plustek:libusb:/dev/usb:/dev/ugen1.2'
is a Canon CanoScan N1240U/LiDE30 flatbed scanner
The nice part about using saned(8) is that you can easily make the
scanner available to other machines on the network. Just add your
network to the server's /usr/local/etc/sane.d/saned.conf and then
add an entry for the server to the /usr/local/etc/sane.d/net.conf
on each of the clients.
