I'd still like to see the output of the above command just to be sure.
Oops, sorry thought I'd checked this but I hadn't.
/dev/usblp0 does not exist. There is a /dev/usb/lp0, however. Here are all
the usb devices:

I think these are all from /dev/.static/dev/. You have to find out which
device node is created for the printer in /dev/ outside of .static.
There is both a /dev/.static/dev/usb/lp0 and a /dev/usb/lp0 (see below -
the non-static one is created when I plug in the printer)
Compare a directory listing before and after you plug in the printer if
necessary. You can use something like
find /dev/ | sort > before.txt
< plug in the printer >
find /dev/ | sort > after.txt
diff -u before.txt after.txt

I need to see the properties of the newly-created device node (and only
of this one). Make sure it is really /dev/usb/lp0.

Udevinfo starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

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
DeviceURI usb://Brother/HL-5040%20series
Looks identical to the /dev name to me.
Most USB DeviceURIs that I find on the web have "?serial=..." appended
after the <model> string. Maybe the problem is that in your case no
serial number is found by the USB backend of CUPS. (I am speculating
here; I never used CUPS with a USB printer.)
Now he tells me ;-)
Seems a little unlikely though as this setup all worked fine with sarge
You could try:
DeviceURI usb:/dev/...
or
DeviceURI USB #1
I've tried
DeviceURI usb:/dev/lp0
which didn't change anything
What about "usb:/dev/usb/lp0"?
Sorry, of course that was what I meant. I have retried in case I
mistyped the actual configuration, not just the email, but still no result
You could also try to find a serial number like this:
udevinfo -a -p $(udevinfo -q path -n /dev/usb/lp0) | grep -i serial
ATTRS{serial}=="L3J497500"
ATTRS{serial}=="0000:00:03.0"
I have tried setting:
DeviceURI usb://dev/usb/lp0?serial=L3J497500
and
DeviceURI usb://dev/usb/lp0?serial=0000:00:03.0
with no results.
Another thing that might be important is how you handled the cupsys
configuration files during the upgrade. Did you keep your old ones or
did you replace them with the maintainer's new versions?
I kept the original version of cupsd.conf, the only file the installer
asked about.
When it didn't work I tried using the new cupsd.conf.dpkg-dist, with no
more success
Also:
After I changed DeviceURI to /dev/usb/lp0, the cups admin panel
immediately showed 'new printer found'. I added this new printer, then
looked at the rewritten printers.conf. The line it had added was the
same as the original version:
DeviceURI usb://Brother/HL-5040%20series
The name cups auto-assigned to the new printer is
Brother_HL-5040_series_USB_1
However, this 'newly discovered' printer also displays 'printer not
connected' when attempting to print to it.
Thanks for your extreme patience!
Graham
