Hi, I saw the recent posting by Roland Jansen regarding the D1250U2 scanner. If nobody is currently working on this driver, I may try to work on it.
It didn't open my D1250U2 scanner to check what is inside, but I think this is the way Roland found his information (?). Unfortunatly, there is no datasheet for the SQ009 on the WEB (the only thing I found was a PCB schematic/eng spec from Philips to build their own scanner - this SQ chip needs very few peripheral components !). I must admit that I have no experience in SANE development but I did some network-protocol reverse engineering, and USB sniffy does not seem that different. Looking at canonscanner.sourceforge.net sourcecode (1220U), it seems that many things relies on : - the register list - the register access protocol I believe that the register list is extremely dependent of the SQ009 chip (do we know - and have drivers for - products which use a SQ00X chip ? Checking for backward compatibility might help). Do you think that the R/W Protocol can be completely different from other canoscan products ? Thanks in advance, Norbert
