Code will be sent for checking committing as soon as final checks are done. Cannot give estimate before available from CVS but in 1 week I should be able to supply test code to interested parties who do not want to wait. My question is, if the 9000F drivers are finished in the meantime? Which sane version is needed? Unfortunately, nothing has been submitted to the CVS repositories yet, so you'll have to get the patched code (pixma_mp150.c) from me. Email me and I'll send it to you. There are about 3 or 4 people that have the code at present. Hopefully between us we will be able to test the remaining modes and fix whatever does not work yet.

[sane-devel] Possible bug in canon backend or scanimage
Dear Stef, I did not manage to compile SANE with the internal getopt_long. At least with my distribution (Ubuntu 10.10) SANE was always built with the glibc getopt_long and disregarding the definitions in the config.h. However I modified the fetch_options function (scanimage.c:859) by adding a line if(opt-name == NULL) continue; at 895. After this modification scanimage works as expected, namely it recognizes all options! May be this is a bug in the glibc implementation of getopt_long (it stops once it reaches NULL option). But I would suggest to modify the scanimage.c. Please find attached the usb log file of the canoscan 8400F. I am not sure if it is complete (the log was recorded while scanner reset and preview, but during the preview I notice that number of recorded packets was not changing). Please let me know if you need more information/tests. The canoscan 3200F I will try during the Christmas holidays.

I find that addition of the --all-options is a nice idea to improve the user interface. Unfortunately it does not solve my problem. This weekend I tried to debug sane to find the source of the error. Just to remind you the problem: scanner canoscan 2700F is supposed to have extra options (reported when using --all-options flag, works with xsane) but this options are not accessible with a scanimage (reported error scanimage: unrecognized option '--af=yes') As was pointed earlier, the message is coming from the getopt_long function (frontend/scanimage.c:2094). With my compilation, the glibc implementation of the getopt_long is used, therefore I could not debug it. However, I have modified the scanimage.c in a way, to printout all command-line parameters and the content of full_optstring and all_options -- parameters of getopt_long function (frontend/scanimage.c:2094). The output you can see in the attachment (scanimage.out.highlight and scanimage.out.af). What I do not like in the output is some (null) option-names in the printed all_options (see line 29 of scanimage.out.af). This (null) string is following after the ae option, which is still working. All options below that (null) line do not work. ??? Option group don't have a name, so it's normal you get null for them. I see nothing obvious from the appended files. You can force the build and use of the internal getopt_long by undef'ing HAVE_GETOPT_LONG in include/sane/config.h, so you can really step in it with a debugger. Here, just in case, few lines which I added to scanimage.c just before while loop at the line 2094 to print parameters: ? ? ???fprintf(stderr,Full_options: %s\n,full_optstring); ? ? ???for(i=0;iall_options_len;i++) ??? ? fprintf(stderr,ap: %s\n,all_options[i].name); Please let me know your opinion on this investigation. I just noticed that there is active development of the genesys backend. I have a canoscan 8400F scanner which is build with the GL843 chip. I would like to help to make backend for this scanner. Please let me know how can I help you. ??? ??? To check how much it is different, we need a usbsnoop log of a preview done under windows. By processing it with scripts, I can extract the information needed to add it to the gl843 scanners. I also have a canoscan 3200F scanner, which I would like to rebuild to a film scanner. But before taking it completely apart I can try to see if we can make it ruining with sane. ??? In older CVS there was an experimental backend for this scanner. Maybe you could look at it. Please find attached the output of the sane-find-scanner utility. Best regards, Myroslav Regards, ??? Stef -- next part -- A non-text attachment was scrubbed...

[sane-devel] Hello, and HP C3180 drivers
Hello all, I've just joined this mailing list, having used Ubuntu 10.04 for a couple of months after 'rediscovering' Linux on an Open University course. I have an old HP C3180 all-in-one Printer Scanner Copier, which no longer prints, but I still want to retain as a scanner. The SANE database online lists it as 'unsupported', so having some (mostly high-level) programming experience I thought I might try to write some drivers for it. I can't get hold of a reference manual for the chipset used, nor find any information about drivers for Linux anywhere else online. First off, does anyone else have any information/code which might help me? It sounds like an interesting and educational project for me to do on my own if necessary, but I don't know exactly where to start at the moment. I've read the page linked on the SANE site (can't remember the author at the moment) about capturing commands from the datastream when the device is accessed under Windows, but I don't really know how to go about this or what software to use. All I have at the moment is the drivers for Windows XP - they might work under Windows7, I haven't tried them on that yet. Can someone tell me how to proceed now please. BTW I've done some assembly language programming many years ago, but that was 6502 stuff on an old BBC Micro, and my knowledge of modern systems at a low level, and PCs in particular, is limited.

[sane-devel] Hello, and HP C3180 drivers
It is possible that this scanner is already supported by the hplip project. They produce a package of sane-compatible drivers, which might already come with your distro. allan On Wed, Nov 10, 2010 at 1:59 PM, Robert Charlesworth rhcharlesworth at googlemail.com wrote: Hello all, I've just joined this mailing list, having used Ubuntu 10.04 for a couple of months after 'rediscovering' Linux on an Open University course.
