This is almost correct: Only root can scan. Do a chmod 666 /dev/usbscanner (as
root user) and you should be in much better shape.

REMOVE THE LINK !!! This is a recipe for desaster - or at least a lot
of trouble. The problem with this is that a lot of backends use /dev/scanner
for their supported SCSI scanners, so you have other backends sending
garbage to your scanner. Not a good thing.

Good.

Try the two things I suggested. If this still does not help, check if 
the scanner is connected to the correct USB driver using:
cat /proc/bus/usb/devices
You should see an entry for your scanner, and somewhere there should
be a "Driver=usbscanner" - if this is not the case, then you  may
have to add a line to /etc/modules.conf to tell the usb scanner driver
what vendor/product ID your scanner has. ... and you also may have to
change the hotplug configuration. But if you can get the driver loaded
with a "/sbin/modprobe scanner" (again, as root) we are at least on
the right track.
