Hi Florian,
Thanks for the response! Answers inline below: basically everything seems
to be right - but cups still thinks the printer is paused...

Hi,
I have a server running cups, with a wireless usb connector connected to
a remote Brother 5040 laser printer. It's always worked fine, modulo a
little crackle on the television when printing ;-)
After upgrading the server to etch (without any major problems) cups no
longer sees the printer. Cups is running ok, and knows about the printer,
but the web interface always displays the message:
" HL5040 (Default Printer) "Printer not connected; will retry in 30
seconds..."
[...]
I guess this is yet another strangeness with changes to udev?That is possible, but it could also be due to the changes between CUPS
1.1 and 1.2. AFAIK, some ways of specifying the DeviceURI have become
obsolete for the new version.
Seems likely, though I haven't spotted the new way in the docs. There's
another etch user on the cups mailing list with a similar-sounding problem
(but no answers).
The obligatory checklist for the udev transition is:
Did you purge hotplug?
apt-get remove hotplug
Reading package lists... Done
Building dependency tree... Done
Package hotplug is not installed, so not removed
Just to be sure: Run
apt-get --purge remove hotplug
(Plain "remove" leaves configuration files on the system; "--purge" gets
rid of them.)
[ snip: kernel 2.6.18-4-486 is OK ]
tail -fn0 /var/log/syslog | sed 's/.*kernel: //'
ohci_hcd 0000:00:03.0: wakeup

Looks like udev is working, but maybe we should check the properties of
the created device node. What is the output of
find /dev/ -name usblp0 -exec ls -l {} \;

series;CLS:PRINTER;"
So far, so good. Now let's see how the printer is defined for CUPS. Post
the output of
grep DeviceURI /etc/cups/printers.conf
Printers.conf can contain passwords in clear text, therefore it is only
readable by root. Make sure to remove confidential information before
posting here. (This is probably not the case for your USB printer, but
better safe than sorry.)
