Thanks to Bertrik and Martijn for advising me to put a link with the logs of my efforts to reverse engineer the protocol of the PrimeFilm 1800u slide scanner.
The web page is: http://www.llama.gs/pf1800i/ BTW, I have made a little progress today as I could start the step motor and produced unpleasant sound when the scanner's head moved out of range. Next I will make some more logs (scanning at max resolution an empty slide, changing only one option to get the differences, etc.) and will try to find some patterns in the log files. Can someone make an educated guess of what this scanner's protocol would look like? I don't believe these guys had created a unique protocol. Any documents of existing drivers? Pple's mind are good in finding patterns but it is much easier with hints. Thanks for the help, -- Alex
