Public bug reported:
Binary package hint: cups
When I try to add a printer via usb-to-parallel, the printer is not
recognized and the backend program will die with a segfault.
Dmesg reports:
[ 4875.810031] usb 3-1: new full speed USB device using ohci_hcd and address 5

The last line can be reproduced by calling /usr/lib/cups/backend/usb by
hand:
