scanimage works, but only when run as root. When I try scanimage as a normal 
user I get the message: scanimage: no SANE devices found. This is similar to

There is certainly only one copy of xsane running. To be certain I tried

debian:/home/barry# xsane
Xlib: connection to ":0.0" refused by server
Xlib: Client is not authorized to connect to Server

Gtk-WARNING **: cannot open display: :0.0
