I have the same scanner-HP3750C. Scanning worked correctly under Jaunty for me (and earlier), so I'm not sure about from the LiveCD specifically. However, under Karmic, the scanner doesn't work at all. When you go to scan, it will communicate with the scanner correctly and start the scan, but it will crash once it gets the image data. People have found that downgrading the libsane file to the jaunty version gets scanning working again (which it did for me, but it makes updating the system a pain because you have to always be aware of the clicking the library update off or redoing the downgrade) since it's on a system I admin for rather than directly control.
Here is the other related bug that has lots o information, but not developer love: https://bugs.launchpad.net/ubuntu/+source/xsane/+bug/428476 I had searched long ago and there some comment from a xsane that something had changed in the backend between 1.0.19 and 1.0.20 that changed one of the APIs and it the versions weren't sync'ed properly, certain of models would break. http://www.xsane.org/ - 2009-2-16 news item. Basically, xsane and sane aren't playing nice anymore past libsane 1.0.19. -- Xsane crashed with HP Scanjet 3570c https://bugs.launchpad.net/bugs/484788 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
