It seems that my message consisting of debug output from the script you sent to test the new genesys code for hp2400 was bounced as being too large. I'm willing to continue trials with that but I also would like to know how to go back to the Elcot code which I have been using for over two years. I suppose the reason it stopped executing was that /usr/bin/scanimage has also been altered.
Can you confirm that if I edit /etc/sane.d/dll.conf to re-activate the hp2400 entry and also comment out the new entry in /etc/saned/genesys.conf then I will be back to running the Elcot .so files in /usr/lib/sane providing I use appropriate arguments in my scanimage command? By the way, I did not include attachments for the image files produced by the debug script (That would have made for an even bigger message.) but I can report that the image is still totally black.
