Did that, still no device found!
However for the first time ever I ignored the warning not to run
as root and xsane found the Canon LIDE-110 scanner and copied as
expected! A permissions problem?
That was on this computer, box6.
Box9 showed "sane-backends-drivers-scanners already installed?"
Box9, as root, found the HP-5370 scanner and copied a page as
expected.
As a matter of interest, my installs are from the XFCE spin on a
flash drive. I then add the applications I want via yum mostly.
Don't know why this computer was different from the other but I
may have inadvertently removed something?
Next to find the permissions problem but this is good progress
for this early hour when I should be sleeping.
Thanks much for your expert help.

There is a simple way to overcome this limitation. Find out what bus the
printer/scanner is on with lsusb. Then go into /dev/bus/usb and change the
permissions of the bus/device that you need access to.

That's what I thought too.
[bobg@box6 ~]$ lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 012: ID 04a9:1909 Canon, Inc. CanoScan LiDE 110
Bus 002 Device 002: ID 046d:c408 Logitech, Inc. Marble Mouse
(4-button)
So I tried changing permissions and then owner.
[root@box6 usb]# ll
total 0
drwxrwxr-x. 2 bobg root 80 Feb 24 11:34 001
drwxr-xr-x. 2 root root 80 Feb 24 10:58 002
drwxr-xr-x. 2 root root 60 Feb 24 04:09 003
drwxr-xr-x. 2 root root 60 Feb 24 04:09 004
drwxr-xr-x. 2 root root 60 Feb 24 04:09 005
There's still "no device available" for user bobg.
Root works, not user.
And even if that did work the device changes whenever I plug in
the scanner, not sure what effect that will have?
