somewhen in the last few weeks, an updates seems to have made my Brother DCP-195C unusable under Ubuntu 14.04 LTS. USB-Connection is given and the printer does work, but the scanner programs either do not find the scanner at all (e.g. sane) or they find it but cannot access the scanner (e.g. scanimage):
user@host:~$ lsusb | grep Brother
Bus 002 Device 008: ID 04f9:0222 Brother Industries, Ltd
user@host:~$ dpkg -l | grep Brother
ii brscan3 0.2.11-4 i386 Brother Scanner Driver
ii dcp195ccupswrapper 1.1.3-1 i386 Brother CUPS Inkjet Printer Definitions
ii dcp195clpr 1.1.3-1 i386 Brother lpr Inkjet Printer Definitions
user@host:~$ scanimage -L
device `brother3:bus1;dev1' is a Brother DCP-195C USB scanner
user@host:~$ scanimage -v -p
scanimage: open of device brother3:bus1;dev1 failed: Invalid argument
user@host:~$ sudo scanimage -v -p
[sudo] password for user:

scanimage: output is not a file, exiting
user@host:~$ sudo sane-find-scanner

The system did work a few weeks ago, so it might be a problem with an update to sane or something similar:
user@host:~$ dpkg -l | grep sane
ii libsane:i386 1.0.23-3ubuntu3.1 i386 API library for scanners
ii libsane-common 1.0.23-3ubuntu3.1 i386 API library for scanners -- documentation and support files
ii libsane-hpaio 3.14.3-0ubuntu3.2 i386 HP SANE backend for multi-function peripherals
ii sane-utils 1.0.23-3ubuntu3.1 i386 API library for scanners -- utilities
user@host:~$ uname -a
Linux host 3.13.0-37-generic #64-Ubuntu SMP Mon Sep 22 21:30:01 UTC 2014 i686 i686 i686 GNU/Linux
So far I've tried re-installing all drivers after purging the old drivers and downloading the current versions from the brother linux support page, but no luck. Also, it's not a permission problem - the output above is the same if run with elevated privileges.
Any ideas or similar behaviors?
Update: The output of scanimage -T passes correctly and the scan head even starts moving around - still no change in the general problem. I also tried rebooting.
