  state made the device opening function error out without comment
  (LP: #987485).
* debian/patches/usb-backend-detach-usblp-earlier-crash-guards.patch: Protect
  against crashes by checking error codes of libusb functions (LP: #997040)

* debian/local/blacklist-cups-usblp.conf, debian/cups.postinst,
  debian/cups.install: Blacklist the "usblp" kernel module again. We have
  now a full-featured USB backend based on the maintained libusb 1.0.x
  and so we can acess printers always through the raw USB devices making
  the module deprecated. Detaching the kernel module for each access causes
  a lot of problems: LP: #902535, LP: #959676, LP: #960666, LP: #987485,
  LP: #995111, LP: #997040, LP: #1000253, LP: #1001028.
