cups 1.4 doesn't find my printer

[Bernd Kosmahl]

Hi,
this is somehow odd. With cups 1.4 I can't print anything. Whenever cups tries 
to access the printer I get this line in dmesg:

usb 2-1: usbfs: interface 0 claimed by usblp while 'usb' sets config #1

I stumbled over http://osdir.com/ml/debian-bugs-dist/2009-09/msg01810.html 
claiming that  usblp must not be loaded for cups to work. I don't have a 
module called usblp nor can I find a kernel option like that.

I reverted cups to 1.4.10 using lin -c -w 1.3.10 cups and after restarting 
cupsd the printer started working at once again.

Any clues?
