did the reply thing - apologies

Please find attached some (slightly edited) output.  I loaded the scanner 
module with the vendor and product id as shown in latest Linux Format mag.  
The scanner is present in /proc/bus/usb/devices but isn't associated with the 
driver - perhaps there is something to modify in the kernel patch?  This is 
now essentially the identical problem I had when I first wrote to the list 
except that an error directly to do with the viceo-backend cropped up as 
well.  Hope this gets us a bit closer.
Tia, Alexis
