    Hi,

    I'm using a Trust Imagery 4800SP scanner on a Tektram SCSI adapter. The scanner seems to start the scan process correctly but both scanimage and xscanimage report a "Device
    BUSY" message just at the end of the scan (no image received).

    What might be the problem here? The output of
    "SANE_DEBUG_MUSTEK=5 scanimage -y 10" is:

    [snip]

    The settings in /etc/sane.d/mustek.conf are:

    scsi MUSTEK * Scanner
      option linedistance-fix # stripes may go away in color mode
      option lineart-fix # lineart may be faster with this option off.

    scsi SCANNER
      option linedistance-fix # stripes may go away in color mode
      option lineart-fix # lineart may be faster with this option off.

    /dev/scanner
      option linedistance-fix # stripes may go away in color mode
      option lineart-fix # lineart may be faster with this option off.

    [commented lines removed]

    Any help is highly appreciated.
    Best regards,
    Andi
