I'll do some more tweaking/testing, try to figure out some of the unknown bits in the protocol and the advanced stuff the Lexmark Windows app can do and make it a bit more robust with resetting the scanner to a good state in case of failure. To compile it with GCC you'll probably need to delete the first line, I've been using tcc to merge compile+run into just run. It needs libusb and libpng installed to compile/run and will write out lexmark_scanner.png to the current directory and a bunch of debugging output to stdout. Hopefully some SANE developer can help me turn it into a SANE backend. I'd also like to know if it is similar to any other scanners that are already supported and maybe an existing driver should be extended. I also wrote a short protocol document, not sure if that is useful to SANE developers or not though. Paul, I put some lexmark2 skeleton files on my homepage, see http://gkall.hobby.nl/dell-810.html My Dell is detected, but no time yet to put the right usb commands in. The Lexmark X2330 usb id are also added. -- m.vr.gr. Gerard Klaver

Maybe using copy of the lexmark backend naming it lexmark2 or copy from logitech1 backend (see http://gkall.hobby.nl/logitech-pagescan-usb.html) to lexmark2 backend?? A quick check on your file seems that there are not many commands needed to do a scan, so pasting into a backend will be not so much work. I can take a look how i can paste it in a copy of the logitech1 backend. -- m.vr.gr. Gerard Klaver

Hi.

Is anyone else working on Lexmark X2330 support? The protocol seems fairly simple at first glance, so it shouldn't be much work if no-one has attempted to get it working yet. I tried to hack compression algo used on Lexmark lx2480 without success. I sort of gave up because it turned out being so difficult to get any sort of controlled data out of it. Every scan is different and lexmark drivers only saves in lossy image format, making comparison difficult. Tying some of the data pins high/low might help with this to some degree. It didn't appear to be adaptive IIRC. http://lists.alioth.debian.org/pipermail/sane-devel/2007-October/020075.html has some speculation and some data if you want to compare. -- Aapo Tahkola

For some Dell 810 inside picture see http://gkall.hobby.nl/dell-810.html Interesting, thanks for the info. I'm not really game to open this X2330 up since it is my sister's one. Looks like that board has an ARM chip on it, you could probably run Linux on there if you wanted :) Do any SANE developers know any of the hardware on that board? I'm really not a hardware person. I have a WinXP machine and did some SniffUSB and usbsnoop2libusb.pl runs today. ?Gerard, do you mind doing some tests if I get a stand-alone driver working? -- bye, pabs http://pabs.zip.to -- next part -- A non-text attachment was scrubbed...
