[sane-devel] Completely supported scanner Canon CanoScan Lide 300 doesn't work

[Kelly Price]

I got a 220 myself and had to get the latest straight from the
project's PPA.  Are you using the SANE Project's PPA?  If not:

sudo add-apt-repository ppa:sane-project/sane-release
sudo apt-get update
sudo apt-get upgrade

That should pull the latest sane packages (Ubuntu/Debian lags hard).
Try it again after getting the latest releases.
