Prior to upgrading my version of Debian on this laptop the Samsung ML-2010 printer was working fine. After the upgrade the printer is no longer recognized as connected to the system by lsusb, though it is seen my usbview. In any case, the GNOME Add Printer utility doesn't recognize the printer as attached.
I have seen other similar reports of problems but I couldn't find a
solution provided.
The syslog snip below shows the printer being initialized at the USB
level.
The usbview log shows the printer being recognized at the USB level.
The lsusb log shows that the printer is not visible in the system.
The user.log snippet shows warnings as relates to CUPS use of the Avahi
Bonjour interface.
So, my hunch (and that is all it is) would be to look at the Avahi
subsystem. However, I am completely unfamiliar with it and not sure what
I'm looking for. Has anyone encountered this issue and resolved it? Does
anyone have any thoughts they would like to share?
Thanks.
Eric
