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.
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.

What about "usb:/dev/usb/lp0"?
You could also try to find a serial number like this:
udevinfo -a -p $(udevinfo -q path -n /dev/usb/lp0) | grep -i serial
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?
