Digital FlatBed Scanner from Hewlet-Packard. It will be nice if SANE will support it in the future. I will appreciate if you can help me to use my scanner on Linux. I hope you find the information sent in this mail useful to workaround the problem. P.S.: How can i get the scanner chipset details without harm (open) the scanner ? Best Regards and thanks.
