This bug was fixed in the package hplip - 3.14.3-0ubuntu3
---------------
hplip (3.14.3-0ubuntu3) trusty; urgency=low
* debian/patches/musb-c-do-not-crash-on-usb-failure.patch: Make sure that
the HPLIP components which access the USB (especially the CUPS backends
"hp" and "hpfax") do not crash when libusb fails to connect to the USB,
for example on machines without USB or with the USB kernel modules not
loaded (LP: #1302437).
