Re: [sane-devel] Adding a scanner backend (genesys) does not work

[Chris Mailer]

Ok, I can give it a try. Where do I start? The only thing to find out
is probably the values for color scales and scan area, if I understand
the config file correctly.
Wouldn't it be a good starting point to just copy these values from a
similar scanner to see how it goes?
Cheers,

Chris

[sane-devel] Adding a scanner backend (genesys) does not work

[Chris Mailer]

Hello,

even though I'm using Linux for some time I barely used a scanner at all.
Whenever I was using a scanner yet, my attempts were quite successful
since the scanners I was using were supported by sane quite good and
were often rather old ones (either SCSI or parallel).
I´m currently trying to get a newer usb-scanner to work, which is,
according the documentation, "to be added to genesys backend"
(whatever that means).
I read a bit further and learned that I would have to activate the
genesys backend in the dll.conf file by uncommenting it (which I did)
and that I would have to add my printer to the genesys.conf file
(which I also did, using the values from sane-find-scanner, "usb
0x04a9 0x2215").
However, neither scanimage nor xsane nor libreoffice would find the scanner.
What else can I do to debug the problem further?

Thank you in advance,

 Chris
