Comment 28 for bug 83587

My scanner HP 5300C worked perfectly until I upgraded to Ubuntu 8.04 TLS. After upgrading, when connecting the scanner, the /dev/bus/usb device is created but is not longer assigned to the group "scanner" but to the group "root", so if I start xsane (as normal user) the device is not detected. If I manually change the device group to "scanner" and then start xsane, the scanner is detected, the program starts but it either segfaults or hangs when I try either the preview or a direct scan.
I have solved the problem simply by downgrading libsane back to the 1.0.18-3ubuntu1 version. After restarting dbus and plugging the scanner off and on again, the device is created properly with "scanner" group and xsane works fine. So it is clear there has been a regression here for libsane.
The only problem now is that update-manager keeps continously annoying me trying to convince me to upgrade again!
