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

[m. allan noah]

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...
