the package I use is: media-gfx/xsane from http://www.xsane.org/

It all points to my Epson scanner even if both scanners are turned on. So, I 
am not able to test it this way. Please provide more info so I can directly 
scan with the Nikon scanner.

Well, this is not sufficent for allowing a user to fully utilize what was 
purchased (in my openion). I purchased this device becaue of all its 
features. Leaving some out would not match purchasing goals.
For sure you know this scanner better than I do just because you are 
deveoloping the driver, but I wish to ask you a question then: How come 
VieScan allows all customizations?

As a matter of fact I was already ready to start my project with this 
application but preferred to wait and see if I could do the same with sane 
(not because of the cost of this package). So I guess sane at this stage is 
not ready for my project. Please confirm me this so that I start it in 
another way.

Also, if you wish for debugging suggest me how to solve my issue with failed 
connection this would be great. Ariel, I am still at your disposal for 
testing and debugging for as much as Linux skills assist me. I hope sane or 
your development will bring the software to a level where full customizations 
and infrared scan become reality.

For now take care,
