Diese Anleitung beschreibt die Einrichtung des SCSI-Scanners Linohell HS5C / Jade.

Für die Installationsarbeiten öffnet man ein Terminal ^[1].

Mit dem Befehl

$ sudo sane-find-scanner -p 

erhält man folgende Meldung:

  found SCSI scanner "LinoHell Office V2.0" at /dev/sg1
  # Your SCSI scanner was detected. It may or may not be supported by SANE. Try
  # scanimage -L and read the backend's manpage.
  # No USB scanners found. If you expected something different, make sure that
  # you have loaded a driver for your USB host controller and have installed a
  # kernel scanner module.
  # No Mustek parallel port scanners found. If you expected something
  # different, make sure the scanner is correctly connected to your computer
  # and you have apropriate access rights.
  # Most Scanners connected to the parallel port or other proprietary ports
  # can't be detected by this program.

Nun weiß man, dass der Scanner am /dev/sg1 hängt. Nun muss die Datei /etc/sane.d/umax.conf in einem Editor mit Root-Rechten ^[2] editiert werden. In der umax.conf steht original noch folgendes:

        # Options for the umax backend
        #
        
        # define scsi queueing depth
        #option scsi-maxqueue 2

        # define how to handle bad sense codes
        #   0 = handle as device busy
        #   1 = handle as ok
        #   2 = handle as i/o error
        #   3 = ignore bad error code - continue sense handler,  
        #option handle-bad-sense-error 0
        
        # define if a request sense command shall be executed

        # define if care-about-smeraring flag shall be set
        # BE CAREFUL WITH THIS OPTION, IT MAY DESTROY YOUR SCANNER WHEN SET

        #option care-about-smearing 0
        
        # define if the calibration shall be done for selected scanarea or for

        # define if an offset of the calculate calibration with has to be used
        # -99999 = auto
        #option calibration-width-offset -99999
        
        # define the number of pixels that is used for calibration
        # -1 = disabled
        #  0 = not set
        #  1 = 1 byte/pixel,
        #  2 = 2 bytes/pixel  
        #option calibration-bytes-pixel -1
        
        # define if scanner uses the same exposure times for red, green and blue
        # -1 = automatically set by driver - if known
        #  0 = disabled (own selection for red, green and blue)
        #  1 = enabled (same values for red, green and blue)
        #options exposure-time-rgb-bind 0
        
        # define if shading data shall be inverted befor sending it back to the
        scanner
        # -1 = automatically set by driver - if known
        #  0 = disabled
        #  1 = enabled 
        #option invert-shading-data 0
        
        # define if the scanner supports lamp control commands
        # 0 = automatically set by driver - if known
        # 1 = enabled 
        #option lamp-control-available 0
        
        # define how 16 bit gamma data is padded
        # -1 = automatically set by driver - if known
        #  0 = gamma data is msb padded
        #  1 = gamma data is lsb padded 
        #option gamma-lsb-padded 0
        
        # define connection type of following devices
        # 1 = scsi

        # Umax Astra 2200 via USB:
        # usb vendor product

        # scsi device list
        option connection-type 1
        /dev/scanner
        
        # usb device list
        option connection-type 2
        /dev/usbscanner

Man muss hier /dev/scanner in /dev/sg1 ändern, also

        # scsi device list
        option connection-type 1
        /dev/scanner

ändern in

        # scsi device list
        option connection-type 1
        /dev/sg1

Jetzt muss man noch die Rechte für den Scanner anpassen. Man legt dazu im Texteditor mit Root-Rechten ^[2] eine Datei /etc/udev/rules.d/10-udev.rules für das udev-System an. Folgende Zeile müssen darin stehen:

# /dev/sg1
BUS="scsi", KERNEL="sg[0-9]*", NAME="sg1", MODE="666", GROUP="users"
