(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, Martin

This scanner is supported according to the SANE page, but doesn't work on my up-to-date C7 system (updated 20 minutes ago). The Canon web site is as expected - as useful as a chocolate tea pot.
Has anyone managed to get this to run, and if so can you share the secret please.
on my C7 system:
# yum list installed | grep -y sane libsane-hpaio.x86_64 3.13.7-6.el7_2.1 @updates sane-backends.x86_64 1.0.24-9.el7 @anaconda sane-backends-drivers-scanners.x86_64 1.0.24-9.el7 @anaconda sane-backends-libs.x86_64 1.0.24-9.el7 @anaconda
and my lide 220 works for me. In previous Centos versions, one had to hack at it because they were shipping old versions of Sane that didn't have the right incantations done over them. I think that (as one other poster mentioned) it involved downloading Fedora source RPMs and building them, or some such. but I had to do none of that for C7.
