[sane-devel] How get scanner commands on kds.log with a Kodak i1440 USB scanner

[Jose Guadalupe Osuna Chavez]

Ok, this will take more time that I was planned. Now I'm using the SnoopyPro too.  :/


I can't adjust the i260 code to the SANE standard yet. I was forced do some dirty things like put many conversion routines in scanimage.c file (frontend level). I'm still working on move all the code to the backend level.

Thanks

use a usb sniffer ( i use the one from here:
http://www.pcausa.com/Utilities/UsbSnoop/default.htm)

unfortunately, it does not decode the meaning of the protocol, so you
are forced to do some pretty serious reverse engineering. If the
machine is not based on a well-known protocol like scsi, it could take
hundreds of hours of work to make a full-featured driver.

oh, and I've not seen any code or patches that support the i260...
