(I know xsane shouldn't normally be run from root - this was just to
eliminate and libusb permission issues.)

I've seen a suggestion that 1.0.26 is required, hence the Fedora
suggestion.  BTW, I tried a "brute-force" Fedora install, but the
dependency hell soon persuaded me of the error of my ways!

Thanks for your suggestion,
