Comment 33 for bug 181242

The device does work perfectly, at least for printing in my case. I'm the only user on this desktop machine, so my username was automatically added during updates/upgrades.
The only problem is that hp-toolbox and hp-info and /usr/lib/cups/backend/hp can't show the info about the printer and printer status when I am a normal user, while it shows ok with root privileges (gksu hplip-toolbox).

And I am included in the group:
$ cat /etc/group | grep -i "lp\|scan\|hp"
lp:x:7:
scanner:x:104:hplip
lpadmin:x:108:username

I even added my username in the lp group, it didn't make any change, the device in hplip-toolbox still has an a big red "x" next to it.

It looks like more of a usb permission problem to me:
