Just got the answer for Hewlett-Packard regarding their plans for ScanJet 55xx support under Linux. They mentioned that scaner protocol specification will never be available public domain as well as any related sources. However, they were so kind to send me beta SANE backend for above mentioned scaner in the binary form. What's interesting that libsane.so (from sane-backends-1.0.14 if memory serves me well) was sent along with the backend without any source. Seems to me that it looks like SANE backends license violation...
I'll try the backend later and will post the results although its usefulness in binary form is near to nothing. Best regards and Merry Christmas, -- Ilia Sotnikov
