This bug affects me two.
It's exatly like Till Kamppeter has described.
Some Ubuntu versions have worked ok, then comes a new one and my hp 1020 stops
working and it's goes on and on.
It's very annoying why can we have this working once and for all.

Bug description:
After upgrading to Ubuntu 14.04 unstable, I can no longer print to my
HP LaserJet 1020.
This is identical to Fedora bug 1047135:
https://bugzilla.redhat.com/show_bug.cgi?id=1047135
`uname -a`: Linux ares 3.13.0-18-generic #38-Ubuntu SMP Mon Mar 17
21:40:06 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
When I plug in my printer, `tail dmesg` looks like this:
[ 4269.639715] usb 2-1.6: new high-speed USB device number 43 using ehci-pci

`lsusb` shows the printer:
Bus 002 Device 043: ID 03f0:2b17 Hewlett-Packard LaserJet 1020
But then when I run `hp-setup`, it's not found:

I do see some error messages in syslog:

And finally, I can strace an hpmud command to see that it fails. (Attached.)
This behavior is consistent with the Fedora bug. It appears like a
broken USB connection, but I've tried two working cables on USB ports
at the back and front of my computer.
