To all those eagerly waiting the CanoScan 3200F backend, some good news and some bad. Let's start with the bad ones: Recently I have had onely few hours per week to put on this work so progress has been very slow. This condition may continue this spring so you can even expect delays to the original schedule. However, I still expect to be able to provide a reflective scanning backend with relatively functionality by the end of May.
The to good news: I have backend that can do reflective uncalibrated gray-scale scans at 75*2**n (n=0-4) dpi. The source code is included with this posting. Now note! The code is highly experimental, likely to contain errors, crappy by outlook etc. etc. Also note: because of this: IF YOU DO NOT KNOW WHAT YOU ARE DOING, DON'T USE IT. At best it may give some hint of where the development is going, at worst IT MAY BURN YOUR SCANNER. So, you were warned! The fuctionality now is that the option setting is basically all in. There are some experimental "features" in the system like setting geometry also moves the head (that was used for verifying the motion and geometry) and that will not be part of actual functionality. Also, many (would like to say, most) options don't reflect to the actual functionality yet. E.g. b&w scan and 16-bits or film mode are not yet there. Also, unstaggering is not yet there and therefore color images appear as three field images and 1200 dpi has the image sensor jaggedness there. What works, is just gray scale scanning and even there you can expect all kinds of problems (like the 1200 dpi jagged image). The image is not calibrated (i.e. no shading calibration). When scanning, starting the scan may take a long time because before every scan the driver checks that the lamp is stable. See the traces described below for what is going on when nothing seems to be happening. Below some instructions of how to compile this in. I do not provide this as a patch to SANE release because of the pre-alpha experimental status. Still, it can be compiled and run, with varying success. ------------------------------------------------------ First, take the latest SANE back-ends from CVS, or any 1.0.17 release (I think any should work since cs3200f does not depend on any recent patches). I would recommend a directory structure $SOMEDIR/sane-backends $SOMEDIR/sandbox if you have SANE already installed. The sandbox dir will be used for installing the compiled backend instead of the actual directories (like /usr/lib/sane etc.) Then put the cs3200f files into $SOMEDIR/sane-backends/backend Put only c and h files. The links will be made automatically in compilation phase. In $SOMEDIR/sane-backends do ./configure --prefix=$SOMEDIR/sandbox BACKENDS="test cs3200f" The test backend is not necessary but will show if your compilation system works when you build it. Now, in dir $SOMEDIR/sane-backends/backend you must add to the Makefile the following lines (e.g. before the line starting libsane-dc25.la: ...) libsane-cs3200f.la: ../sanei/sanei_constrain_value.lo libsane-cs3200f.la: ../sanei/sanei_thread.lo libsane-cs3200f.la: ../sanei/sanei_usb.lo libsane-cs3200f.la: ../sanei/sanei_access.lo libsane-cs3200f.la: ../lib/md5.lo Now in dir $SOMEDIR/sane-backends do make and check that it works OK. E.g. in $SOMEDIR/sane-backends do make >make.log 2>&1 In make log there may be warnings but compilation of cs3200f.c should give no warnings or errors. If it does, drop me a note with log (compressed please :) ). The make may end in error in makin sane.ps but that do not worry about, that's just docs. Then do make install and you should now have the cs3200f libraries in $SOMEDIR/sandbox/lib/sane. Now become a root and copy the cs3200f lib files to /usr/lib/sane or where ever your xsane expects the libs to be. Then in /etc/sane.d (or wherever you find the dll.conf for sane dll lib) add to the dll.conf line cs3200f and if you wish, uncomment test backend. Now run xsane. You should have test backend and cs3200f:dummy devices available (do not plugin the scanner, if you plugin the scanner, the real one instead of dummy you shall get). :) Now, into directory $SOMEDIR/share/sane/cs3200f put the firmware file cs3200f_v0054.fw you have created following the instructions I previously posted in sane-devel. http://lists.alioth.debian.org/pipermail/sane-devel/2005-December/015769.html Now, if you plug in the scanner and restart the xsane you should actually be able to boot the sanner and then moving the top left y cordinate will actually move the scan head, and pressing the calibrate now, will calibrate the AFE (that takes some time if lamp is not warmed up). These are just for testing the driver and thus do not reflect the actual final functions of these controls. Warning: if you hear strange noises from the scanner, unplug the power adapter immediately. Then reset the scanner with windows driver and check that it still works OK. This "should" hot happen but happened to me several times when figuring out the command set. If you suspect problems, have the following env vars exported: export SANE_DEBUG_CS3200F=255 export SANE_DEBUG_SANEI_USB=255 export SANE_DEBUG_SANEI_ACCESS=255 and start xsane from a command line like xsane >xsane.log 2>&1 Send me the log, compressed, or try to figure out where the problem is. That should do it. If not, drop me a note. ------------------------------------------------------ Known issues: There may be problems with communications with the scanner if you are running a fast processor (this was found by Kristian Fiskerstrand, thanks!). It may happen, e.g., that after uploading the firmware reading it back fails and thence the boot fails. I will take a look at those speed issues later. Now, if you decide to try the code, and find problems with it, drop me a note. I won't correct everything immediately, but I will make notes of all known issues to take care of later, when all the basic functionality is in.

Problem solved, apparently. I was running a late 6.0-STABLE (from just before RELENG_6 became 6.1-PRERELEASE), and upgrading to 6.1-PRERELEASE has the scanner working now. Beats me. Jeff
