Hi Klaus, Jörg,
[... Ubuntu using libsane1-1.0.27-1~experimental* packages breaks just
about any third party SANE backend package ...]
1. Brother: brscan, brscan2, brscan3
2. Epson Iscan
3. Xerox Workcentre 3225
I read through the bug report you mentioned below and think the whole
thing sucks. 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*experimental* package for their upcoming release just to get a newer
version of the SANE backends upstream.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.
@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
Some people call using 'MODE="0777" for epson dangerous. The rule was
installed by the epson-printer-utility. With the rule Iscan works,
A mode of 0777 gives anyone on the PC/laptop access to the scanner (MFP
in your case, I believe). 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.
Hope this helps,
