Hi, I am new on this list and new to debian and SANE. I have done the best I can to try and troubleshoot this scanner myself, but have not succeeded. I think the problem is with SANE, but I am not sure this is the appropriate place to ask for help. If it is not, please let me know if there is someplace I can ask for help with this.
That said, here is the problem I am having: I am trying to get SANE to work with microtek scanmaker 4800. It opens the front end, whether xscanimage or xsane, but freezes upon trying to scan. Because it fails in both front ends, I am assuming the problem is either with the back end or communication with it. I read sane-problems-doc.html and followed the instructions as best I could. Here is what I've tried so far: uninstalled sane, xsane, and libsane, reinstalled. I did this because I installed the driver for scanmaker 4800 myself rather than through the package installer, so I guessed that uninstalling and reinstalling would write the correct files. I found out later that the driver, sm3840, is included in the distribution for sane or xsane so I did not need to install it seperately. Perhaps I need to do more to uninstall the file I installed, but I don't know if that is the case or how to tell. then I commented out all other scanners and net in /etc/sane.d/dll.conf. The troubleshooting instructions say it should be in /usr/etc/sane.d/dll.conf, but I am assuming the different location is from how the debian package installer installs it. made sure only one version is installed removed config directories from home dir searched for g*-config...found neither gtk-config nor gimp-config ran gdb scanimage with following result: ...

(..." indicates prior line repeating many times) front end opens, finds scanner sm3840, but freezes when I hit scan or preview, and I have to force a quit. gdb still does not return, so hit ctrl-C, which returned to gdb prompt after giving message: Program received signal SIGTSTP, Stopped (user).
