Bug Description
I have a Brother MFC-7420 printer/scanner combination device. It was working when I had Ubuntu 12.04 LTS installed. I have installed the Brother drivers from the Brother website (brscan2 version 0.2.5-1).
When upgrading to Ubuntu 14.04 LTS scanning stopped working as a normal user, neither Simple Scan nor Xsane found the scanner. When launching as root, both were working (e.g. sudo simple-scan).
The problem was related to the scanner device (/dev/usb/lp0) belonging to the group lp, with normal users having no access permissions to the device file. When I added my user account to the lp group, it solved the issue.
Curiously, sane-find-scanner still cannot find my scanner, but scanimage -L works, as well as simple-scan and xsane.
The same problem has been discussed here, concerning Ubuntu 13.10 (I'm running 14.04 LTS 64bit):
