Comment 4 for bug 1315408

Same story for a Hp Laser Jet P1007 user (http://askubuntu.com/questions/464651/problem-with-printing-hplip-in-ubuntu-14-04/488484#488484)

Somebody tried cups 3.14.6 and it failed in the same way:

In rare cases the printer *is* recognized, especially immediately after boot (or repeately power-cycling the printer and USB). This makes me think there is some timing problem in detecting the printer in kernel or loading corresponding firmware.
