Hi Peter
This would suggest that the scanner needs the epkowa driver (or another driver
which would be bad news) to function properly and that the driver isn't
loaded.
I would suggest checking the filelist of the sane and iscan rpms you have
installed to make sure that the iscan driver is in the right directory and
also the file /etc/sane.d/epkowa.conf to make sure that keyword "usb" is
present and uncommented.
The usb keyword can also take the usb vendor id and product id of your scanner
as parameters if it isn't automatically detected
Regards
Dave

Not much time to do much atm, just did a bit of googling and think it
should work with epkowa.
Does this driver exist in "sane-backends" if not how do I find it?
I had a look at some older info and "avasys" seems to be just a Chinese
site now.
