[Pkg-cups-devel] Bug#545288: CUPS 1.4.0-4 doesn't find USB-printer

[Oleksandr Natalenko]

Package: cups
Version: 1.4.0-4

After upgrading CUPS to 1.4.0 branch it doesn't find my USB-printer anymore. 
When I click «Add printer» in CUPS web-interface, my printer doesn't appear in 
the list. «Find New Printers» button also doesn't help.

dmesg shows me:

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

while CUPS is trying to find the printer.

My system hasn't AppArmor or SELinux.

My printer is Xerox 3117, also tried Xerox 3121. Kernel version is 2.6.30.5 
with BFQ I/O scheduler.
