(I know you realise) I was posting to indicate that between upgrades some 
devices that were working, stop working (it is my experience that they start 
working again one upgrade later).  

The scanner is the canoscan 670u and is auto detected by YaST and assigned the 
plustek driver.  It successfully acquired a test image during set up.  The 
scanner used to work through kooka in 9.0.  Until 9.1  I have not needed to 
touch xsane.  

Currently Yast describes the device as "libusb" 

However I cannot find that device in /dev/usb to test xsane 
[plustek:/dev/usb/libusb] [-s] from the command line (so kooka and indeed the 
gimp are irrelevant at this time) 

The entries dev/usb/ contains are [scanner0] [scanner1] etc.

It reminds me of the printer problem that I couldn't solve when I upgraded 
from 8.2 to 9.0.  Then

echo -en "\rHello\r\f" >/dev/usblp0  

worked, but
 
echo -en "\rHello\r\f" >/dev/usb/lp0      

did not work and CUPS seemed to be looking for the latter entry.
I tried symbolic linking but could not solve the problem.

I cannot find libusb anywhere so even if I had confidence in my ability to 
correctly create a symbolic link, I am not sure that it would be any use.

TIA
