usb scanner setup

[Sandy Pond]

I needed to add;

usb 0x04b8 0x0110

to /etc/sane.d/epson.conf to be able to talk to my Epson 1650 scanner
and;

chmod 777 $(sane-find-scanner | \
            grep '^found USB scanner' | \
            sed -e 's?^.*libusb:?/proc/bus/usb/?' -e 's?:?/?')

to /etc/rc.d/rc.local so that normal users could use it.  Is there a bug
here or is this the normal configuration procedure (I'm glad ESR didn't
try to setup a usb scanner)?
