    To see details about what the backend is doing use

    SANE_DEBUG_PLUSTEK=255 scanimage -L
    SANE_DEBUG_PLUSTEK=255 xscanimage
    SANE_DEBUG_PLUSTEK=255 xsane

    Be sure to read the INSTALL and PROBLEMS files (for the frontends)
    concerning the library paths in /etc/ld.so.conf.

    Another idea: Maybe xscanimage has other permissions (suid root?) then
    xsane?

    Bye,
