I tried to extract some useful information about the crash from /var/crash/_usr_lib_cups_backend_usb.0.crash, but all apport tools fail to do anything useful (can't detect a package, etc.).
Probably because cups package contains /usr/lib/cups/backend-available/usb
But crashing executable is /usr/lib/cups/backend/usb. A hard link to /usr/lib/cups/backend-available/usb.
