[arch-general] Scanner only works as root

[Renan Birck]

Hello,

I have an HP Photosmart C3180 all-in-one (printer/scanner/copier). 
Installed cups, hplip, sane.

Printing works. Scanning, however, only works as root, otherwise xsane 
says that there are no devices.

But if I chmod 777 -R /dev/bus/usb/* it works for my current user; 
therefore I deduce it is a permission problem. This looks like an udev 
problem, however my udev knowledge is next to null.

What steps could I take to solve this problem? I would like to get rid 
of this ugly hack.

Thanks.
