NAME

       sane-sm3600 - SANE backend for Microtek scanners with M011 USB chip

DESCRIPTION

       The sane-sm3600 library implements a SANE (Scanner Access Now Easy) backend that provides access to some Microtek scanners with the Toshiba
       M011 custom USB chip.  This backend should be considered alpha.

       There exist a backends for Microtek scanners with SCSI command set.  Refer to sane-microtek(5) and sane-microtek2(5) for details.

       At present, the following scanners are known positively to work with this backend:

	      Vendor	 Product id:	 Remark:
	      --------	 --------------  -----------
	      Microtek	 ScanMaker 3600  all modes ok
	      Microtek	 ScanMaker 3700  reported to work
	      Microtek	 ScanMaker 3750  reported to work

       If you own a Microtek scanner with the M011 chip other than the ones listed above, it may or may not work with SANE!

FRONTEND OPTIONS

       This backend dynamically enables the options for the frontend, that are supported by the scanner in dependence  of  the	scanning-mode  and
       other options. Not supported options are disabled.

       The following options are supported by the Microtek2-driver:

       Color, grayscale, halftone and lineart scans.

       contrast, brightness, control, gamma correction.

DEVICE NAMES

       This backend does not support device names in a standardized form.

CONFIGURATION

       This backend does not support a configuration file right now.

FILES

       /usr/lib/sane/libsane-sm3600.a
	      The static library implementing this backend.

       /usr/lib/sane/libsane-sm3600.so
	      The shared library implementing this backend (present on systems that support dynamic loading).

PERMISSIONS AND INTERFACES

       The  backend  uses  libusb  and	it's pseudo files in /proc/bus/usb/*. Since libusb versions 0.1.3b and 0.1.4 have incompatible binary data
       structures, You must be shure not to have obsolete header files. When You mix wrong versions, the scanner detection code will raise a "seg-
       ment violation".

       These files are normally owned by root and You are responsible to get access to these files, for example chown-ing them to Yourself. If You
       have no right permissions, the backend will find the device, but You'll get an I/O error.

       The better way is to use automatical hotplugging. See http://sm3600.sf.net/hotplug.html for instructions and useful links.

ENVIRONMENT

       SANE_DEBUG_SM3600
	      If the library was compiled with debug support enabled, this environment variable controls the debug level for this backend.   E.g.,
	      a  value	of  128  requests  all	debug  output to be printed.  Smaller levels reduce verbosity. To see error messages on stderr set
	      SANE_DEBUG_SM3600 to 1.

	      E.g. just say:
	      export SANE_DEBUG_SM3600=5
