Natty: sane_start says "Device busy" [RESOLVED]
« on: June 29, 2012, 00:17:09 »
Hi there - Until recently both my scanner and printer (SCX-3205W) were working just fine (thank you) on over the network using Ubuntu 11.04.

Now, printer works as expected but scanner doesn't: sane_start gives me "Device busy".

/var/log/apt/history.log says:

Start-Date: 2012-06-13  21:33:50                                                 
Commandline: apt-get upgrade                                                     
Upgrade: samsungmfp-network:amd64 (4.00.35-1, 4.00.35-2), samsungmfp-scanner:amd64 (4.00.35-1, 4.00.35-2), samsungmfp-driver-4.00.35:amd64 (4.00.35-1, 4.00.35-2), samsungmfp-configurator-data:amd64 (4.00.35-1, 4.00.35-2), samsungmfp-common:amd64 (4.00.35-1, 4.00.35-2), samsungmfp-data:amd64 (4.00.35-1, 4.00.35-2), samsungmfp-driver:amd64 (4.00.35-1, 4.00.35-2)
End-Date: 2012-06-13  21:35:58 

If I read this correctly the update was from 4.00.35-1 to 4.00.35-2. If so, how can I revert back to 4.00.35-1?

Thank you!

The only change between those two versions was the dependency on libtiff, which should have no impact at all on scanner detection.  Rather than downgrading, you can test if it is having an impact by:
Code: [Select]
sudo mv /usr/lib/libtiff.so.3 /usr/lib/libtiff.so.3.old
Then try the scanner again.  To revert the above:
Code: [Select]
sudo mv /usr/lib/libtiff.so.3.old /usr/lib/libtiff.so.3
If it works after the first mv command and then stops again after the second, it is related to these packages.  You can also test by running:
Code: [Select]
/opt/Samsung/mfp/bin/netdiscovery --all --scanner
It should output information about your scanner.

If it's not the libtiff issue or a problem with netdiscovery, it's something else; were there other updates to your system since you last used the scanner, particularly packages with "sane" or "udev" in the name?

Turns out the scanner died on me.

Thanks for the timely support.
