Mustek 1200UB Scanner

There is no kernel module

The Mustek 1200UB scanner does not require a kernel driver module, instead using the libsane userspace library for operation.

Required packages

The following package suites are required to operate the flatbed scanner:

* sane * sane-utils * libsane

Checking the scanner for connectivity

The lsusb tool should show the scanner attached to the usb port:

  • lsusb

    Bus 001 Device 003: ID 055f:0006 Mustek Systems, Inc. ScanExpress 1200 U

The sane-find-scanner tool should identify the scanner as usable:

  • sane-find-scanner|grep "^found" found USB scanner (vendor=0x055f, product=0x0006, chip=MA-1017) at libusb:001:003

System groups for scanner users

In order to be able to operate the scanner as a normal user, it is necessary to become a member of the scanner system group.

As root, create this group, if it does not exist on the system:

  • groupadd -g 23 scanner

As root, add users to the scanner group:

  • gpasswd -a foobar scanner

Configuration of sane for utilization of the scanner

The !/etc/sane.d/mustek_usb.conf configuration file should contain the following entries:

  • # Autodetect 1200 UB and Trust Compact Scan USB 19200 usb 0x055f 0x0006 /dev/bus/usb/001/003 option 1200ub

Notice that 001 and 003 correspond to the USB bus and device numbers and must be set to values that match the numbers identified by lsusb above.

Making the usbfs filesystem mountable

The libsane userspace library can only access the scanner if it is not claimed by the kernel scanner driver. The usbfs filesystem must be mounted in order for libsane to be able to operate. The !/etc/fstab configuration file should contain the following entry:

  • none /proc/bus/usb usbfs defaults 0 0

Creating the udev entries

It is now necessary to create the /etc/udev/rules.d/libsane.rules file with entries as follows:

  • # This file was automatically created based on description files (*.desc) # by sane-desc 3.5 from sane-backends 1.0.21 on Sun Dec 12 16:18:21 2010 # ACTION!="add", GOTO="libsane_rules_end" ENV{DEVTYPE}=="usb_device", GOTO="libsane_create_usb_dev" SUBSYSTEMS=="scsi", GOTO="libsane_scsi_rules_begin" SUBSYSTEM=="usb_device", GOTO="libsane_usb_rules_begin" SUBSYSTEM!="usb_device", GOTO="libsane_usb_rules_end"

    # Kernel >= 2.6.22 jumps here LABEL="libsane_create_usb_dev"

    # For Linux >= 2.6.22 without CONFIG_USB_DEVICE_CLASS=y # If the following rule does not exist on your system yet, uncomment it # ENV{DEVTYPE}=="usb_device", MODE="0664", OWNER="root", GROUP="root"

    # Kernel < 2.6.22 jumps here LABEL="libsane_usb_rules_begin"

    # Mustek ScanExpress 1200 UB | Trust Compact Scan USB 19200 ATTRS{idVendor}=="055f", ATTRS{idProduct}=="0006", MODE="0664", GROUP="scanner", ENV{libsane_matched}="yes" # The following rule will disable USB autosuspend for the device ENV{libsane_matched}=="yes", RUN+="/bin/sh -c 'test -e /sys/$env{DEVPATH}/power/

    level && echo on > /sys/$env{DEVPATH}/power/level'" LABEL="libsane_usb_rules_end" SUBSYSTEMS!="scsi", GOTO="libsane_scsi_rules_end" LABEL="libsane_scsi_rules_begin" # Generic: SCSI device type 6 indicates a scanner KERNEL=="sg[0-9]*", ATTRS{type}=="6", MODE="0664", GROUP="scanner", ENV{libsane_matched}="yes" # Some scanners advertise themselves as SCSI device type 3 KERNEL=="sg[0-9]*", ATTRS{type}=="3", ATTRS{vendor}=="HP", ATTRS{model}=="C7670A", MODE="0664", GROUP="scanner", ENV{libsane_matched}="yes" LABEL="libsane_scsi_rules_end" LABEL="libsane_rules_end"

A template file may be available

Note that a template file may be available in the /lib/udev/rules.d directory. Do not symlink this file. Instead copy it to !/etc/udev/rules.d/libsane.rules.

The scanner will be available for use when the system is restarted

The udev system will need to evaluate the new rules, and fstab will need to be evaluated in order for the above changes to take effect. This will occur automatically, when the system is next rebooted.

Producing a test scan

A test scan can be produced by placing a picture into the scanner and using the following command:

  • scanimage --mode color --resolution 300 >image.pnm
