Did you recompile and reinstall modified version of SANE?? Also did
you add flag GENESYS_FLAG_UNTESTED in Genesys_Model structure??

you may need to add your model specific code. Check genesys_gl841.c
>
In genesys_devices.c file you will find other structures also
like motor,sensor specific information of your model need to be filled
there. For that you need to download usbsnoppy from
http://benoit.papillault.free.fr/usbsnoop/doc.php.en
and use that on Windows and capture some log. For that you can search
archives of this mailing list about how to capture USB packets on
windows and then apply awk scripts to generate decoded log and use
that to fill those structures. Attaching those scripts that need to be
used on linux with use of usb packets captured windows log file.

Subject: [sane-devel] Epson 4490
Message-ID: <1148995947.16977.25.camel@localhost2.localdomain>
Hey all. I bought an Epson 4490 but am having some problems. Some
being Infrared, 16 bit color and 4800dpi support with Sane.
The other, I'm having some h/w issues and Vuescan. Vuescan uses a motor
speed with Pass #2 causing clicks during scan element initializing and
vibration with the particular speed used for Pass #2 -- probably not a
good thing when scanning at 4800 dpi and making 1+ passes!
The windows software, although uses quieter motor speeds, quality is
lacking and the Epson Windows software seems to really kill the color on
the scanned images (not using ICC profiles).
Another minus, both Windows and Sane seems to lack RAW image support
except for Vuescan?
Anybody have any suggestions for scanning 35mm negatives? I really
need something that supports Infrared or Digital ICE from what I see
from allot of my scans.
(Epkowa seems broke in my latest sane compiles, but am curious if epkowa
has plans for infrared, etc., Who and where to help out with Epkowa Sane
Backend?)
