Detected scanner fails to open device, "Invalid Argument"

[TomTasche]

Hello,

I've installed the latest drivers from the Brother support website for my Brother DCP-165C. Printing works fine, but I can't get scanning working... I have followed all instructions provided by the Brother support website (udev rules, etc). I'm running Ubuntu Server 11.10.

No matter whether I'm running scanimage (or xsane) as sudo or not, I'm getting the same error message:
"scanimage: open of device brother3:bus2;dev1 failed: Invalid argument"

You can find a strace attached (ran with sudo).

Some more outputs:
scanimage -L
device `brother3:bus2;dev1' is a Brother DCP-165C USB scanner

  # result is different from what you expected, first make sure your
  # scanner is powered up and properly connected to your computer.

  # No SCSI scanners found. If you expected something different, make sure that
  # you have loaded a kernel SCSI driver for your SCSI adapter.

Status changed to 'Confirmed' because the bug affects multiple users.

This looks like duplicate of https://bugs.launchpad.net/ubuntu/+source/xsane/+bug/478761.

Using a suggestion there, I worked around this by adding myself to group lp and then restarting.
To do this using the command line:
groups yourusername
usermod -G allyourgroups,commaseparated,lp yourusername
