Thank you very much. As recently as sane-backends-1.0.16 with the avision source of build 280, I had never been able to get my 5370C working correctly. I applied your patch against sane-backends-1.0.16--it wouldn't apply properly to the version of avision that I got from SVN--and the scanner worked very well.
I still do not know what was causing my prior failures, but I know that this patch made almost everything work. The only problem that exists right now is that I do not have a "preview image." This is true in both <xscanimge> and <xsane>. When I select "acquire preview," the scanner scans, but there is only a grey, with lightly colored lines, image in the preview window. As a result, I must scan multiple images, adjusting the parameters of gamma, brightness and contrast, until I get a good image. I have generated a log file with the debug level set at 10. There's lots and lots of output. Is there anything for which I can "grep" or should I lower the debug level and send the complete results? Once again, both Rene and Falk, thank you. Dan
