Comment 13 for bug 121082

Sim: is that really apt-get -f install with no package names after it?

I'm having this problem too -- my scanner which worked fine under gutsy and earlier no longer works unless I figure out which USB device it is and sudo chmod 666 or sudo chgrp scanner. The udev rule

Copying the /etc/udev/rules.d/45-libsane.rules from my gutsy partition into hardy seems to cure the problem -- now the USB device is group scanner and I can access it. I'd rather not have my scanner depend on hal anyway.
