Ubuntu has made a *huge* judgement error pulling an *experimental* package for their upcoming release just to get a newer version of the SANE backends upstream. A lot of scanners supported by third party scanner break for no good reason. I think things can actually be solved quite easily if Jörg can upload a libsane-1.0.27 package that simply uses the debian/* from 1.0.25 with a few minor changes: - change the configure invocation to account for the changed USB option (see note 2 of the NEWS file) - drop any patches that we included (mentioned in an earlier head's up) - the usual "new version" changes This can be uploaded to Debian's unstable/sid and Ubuntu can then pull that for their upcoming release. > Any help/advice appreciated. See above. @Jörg> You can stop reading here and start on that package ;-) > The owner of the brscan4 Scanner asked Brother. They replied: "read the > faq, or check over internet if there are solutions from the community". That's a polite way of saying "We don't support GNU/Linux" :-( Brother is not alone in this. Manufacturers may publish a package that makes the device work with (a subset of?) SANE but that is not the same as providing support. > current state can be observed here > https://bugs.launchpad.net/ubuntu/+source/sane-backends/+bug/1728012 Ugh! > Some people call using 'MODE="0777" for epson dangerous.

Whether that is "dangerous" depends on who uses th PC/laptop. The idea behind 0664, used by many distributions, and making the device owned by a special purpose group (scanner, lp, etc.) or adding an ACL for that group is that that allows the machine's admin to configure some kind of access policy. I think that 0666 should work but that basically has the same security implications. I don't know if the printer utility has any special requirements that dictate execute permissions and also don't know what is responsible for the firmware upload. I do know that the non-free scanner plugin are (should be) able to upload the firmware themselves.
