Read that already. In searching to solve the problem, I found that several 
days back. Unfortunately it does nothing to solve the problem. The README 
simply says that the files "libsane.usermap" and "libusbscanner" should be 
in /etc/hotplug/usb and they are. But they do nothing to elicudate the 
problem or solve the problem. The README further reads that the solution to 
the problem is simply to add the user(s) to the "scanner" group. 
Unfortuantely the scanner group did not exist. I created the group and added 
the desired users to the group, but that had absolutely no effect whatsoever. 
So I am still back to the only effective solution given in the README (which 
I had already found) and that is to 

su -c 'chmod a+rw /proc/bus/usb/001/003'

and then repeat after each boot.

Not really a satisfactory solution. Want that done automatically at boot time.

Thanks and Still trying,
