Please note that I am aware of the emails on this issue from last August
12th where the solution presented is snipped below. I did add the line
module/usbcore/parameters/autosuspend = -1
to the /etc/sysfs.conf after installing sysfs and rebooted and still the
printer remains unseen.
However if I follow Benjami's suggestion to:
# echo -n 60 > /sys/module/usbcore/parameters/autosuspend
then the printer is listed in lsusb.
There is something that I've missed. Any thoughts?
Thanks to all for any suggestions or thoughts.

Solved!

to /etc/sysfs.conf
Thanks, Krzysztof and Ron!

Subject: Samsung ML-2010 Printer Not Recognized as connected to system
Date: Sun, 30 Dec 2007 18:49:21 -0500
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
