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:

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
and
DeviceURI USB #1
which gave me the cups error message:
Backend /usr/lib/cups/backend/USB does not exist!
and
DeviceURI usb #1
which gave me the cups error message:
No device URI found in argv[0] or in DEVICE_URI environment variable!
Best

instead. (Replace "..." with the exact path to the device node. Run
"invoke-rc.d cupsys restart" or "/etc/init.d/cupsys restart" after
editing printers.conf.)
