[sane-devel] scanbd problem with dbus permission ?
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1
Hello,
Something strange happened :
2 months ago,I managed to get scanbd to work perfectly with my epson
V500 scanner, built my own script, ..., was very proud of myself...
... until today, where after 2 months of not using it, I tried to use
a button, and it did not work !!
I must have changed something, during those 2 months, but I really
don't know what...
So, the scanner is plugged in a Debian 6,
the debug log shows these errors :
scanbd: start dbus thread
scanbd: Not Primary Owner (-1)
scanbd: Name Error (Connection ":1.8" is not allowed to own the
service "de.kmux.scanbd.server" due to security policies in the
configuration
and later :
scanbd: polling device Perfection V500
scanbd: epson-vphoto-backend: communication error: read length:0
(expected:1)
(the full log is pasted afterwards)
I tried to modify the user/group in scanbd.conf (trying lp, saned,
scanner, root..) with no change.
The UDEV rule for the scanner seems to make it belong to the "scanner"
group :
ATTRS{idVendor}=="04b8", ATTRS{idProduct}=="0130", MODE="0664",
GROUP="scanner", ENV{libsane_matched}="yes"
Don't hesitate to ask me for more informations if needed...
Thanks for your help !
best regards
stout
here is the full log :

I would call it at least 'Good'. I have used this code to scan over a
hundred negatives. But then only I have used it. Others may want
something else. I am open to adding to it although I would prefer to get
an initial implementation committed before doing so.

[sane-devel] gscan2pdf v1.1.3 released
gscan2pdf - A GUI to produce a multipage PDF or DjVu from a scan. http://gscan2pdf.sourceforge.net/ Only two clicks are required to scan several pages and then save all or a selection as a PDF or DjVu file, including metadata if required. gscan2pdf can control regular or sheet-fed (ADF) scanners with SANE via libsane-perl, scanimage or scanadf, and can scan multiple pages at once. It presents a thumbnail view of scanned pages, and permits simple operations such as cropping, rotating and deleting pages. OCR can be used to recognise text in the scans, and the output embedded in the PDF or DjVu. PDF conversion is done by PDF::API2. The resulting document may be saved as a PDF, DjVu, multipage TIFF file, or single page image file. Changelog for 1.1.3: * Added missing arguments to 'changed-progress' signal emission. * Fix bug preventing import after error. Closes bug 155 (can't enter correct file name after incorrect file name) * Fixed bug introduced in v1.1.2 causing only one page to be scanned when all requested * Fixed bug introduced in v1.1.2 causing two pages to be scanned when only one requested

Dear Andrew, dear Oliver, why not discuss this publicly on this list too. 1. People having a BenQ ScanWit 2720S might join the discussion and test the patches too. 2.
