Hi everyone,<br><br>I'm new to this list so please forgive me if my post is inappropriate or has already been answered a multitude of times.<br><br>I would like to know if there is anyone around actively working on getting the Canoscan 4200f within the supported models of sane?<br>
Is anyone aware of any working solutions under Linux (ubuntu)<br>I took a few tentative steps to look into the back end support. It is Identified by "sane-find-scanner" <br>

<p style="margin: 0px 0px 0px 40px; text-indent: 0px;"><span style="font-family: 'Courier New,courier';">found USB scanner (vendor=0x04a9, product=0x221b, chip=GL841?) at libusb:001:008</span></p>

but not listed using "scanimage -L"<br></p><p style="margin: 0px 0px 0px 40px; text-indent: 0px;"><span style="font-family: 'Courier New,courier';">no scanner found</span></p>Quite a bit is already know of the scanner: <span style="font-family: 'Courier New,courier';"><a href="http://www.sane-project.org/unsupported/canon-4200f.html">http://www.sane-project.org/unsupported/canon-4200f.html</a></span><br>
<br>I also installed usbsnoop on my sons windows box and was successful in getting a 600mb log file for two commands to the scanner (preview and scan). It sure looks like the snooper is working but without usb protocol knowledge, its quite worthless information for me. Can anyone help me get started to condense the log file and identify the relevant parts for analysis? I would also need to know which commands need to be logged in the backend build process.<br>
<br>In short, is there a experienced sane back end developer that would have the time and energy to work with me to get the scanner working under sane? I am willing and capable to give timely feedback on the interactions of the windows driver as well as testing and debugging in Linux. Left alone, I fear I will not take on the challenge to become a sane backend developer :s<br>
