Yep...I was a bit quick on the trigger.  Object lesson: IT PAYS TO READ 
THE HANDBOOK!:-)   But thank you for responding.  Once I created the usb 
group and put the appropriate entries in /etc/devfs.rules all was well.  
This was a good learn for me, however, since I now understand the 
difference between devfs.conf and devfs.rules.

Cheers...
