  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,
