       sane-canon630u - SANE backend for the Canon 630u USB flatbed scanner

       The  sane-canon	library implements a SANE (Scanner Access Now Easy) backend that provides
       access to the following Canon flatbed scanners:

	      CanoScan 630u
	      CanoScan 636u (hopefully)

       IMPORTANT: this is alpha code.  Although there are no known bugs at this time,  this  code
       uses  the  Linux USB kernel drivers, which are currently in active development.	So it may
       not work, your computer might even hang, and it cannot be excluded (although I consider it
       extremely unprobable) that your scanner will be damaged.

       That  said,  TESTERS  ARE  WELCOME.  Send  your	bug reports and comments to Nathan Rutman

       This backend expects device names of the form:


       Where special is the path-name for the special device that corresponds to a USB scanner or
       a  symlink  to such a device.  The program sane-find-scanner helps to find out the correct
       device. Under Linux, such a device name could be /dev/usb/scanner0 for example.	See sane-
       usb(5) for details.

       The contents of the canon630u.conf file is a list of device names that correspond to Canon
       USB scanners.  Empty lines and lines starting with a hash mark (#) are ignored.	Only  one
       device name can be listed in canon630u.conf.

       Due to Canon's unwillingness to provide scanner documentation, this software was developed
       by analyzing the USB traffic of the Windows 2000 driver.  So things like  the  calibration
       procedure I kind of made up; it seems to work for my scanner.  If you have complaints, let
       me know.

       This driver requires the ability to send USB Control Messages, available in kernel  2.4.12
       or later.

       This scanner may not be recognized (yet) by the USB kernel driver.  Check for "Driver=usb-
       scanner" under /proc/bus/usb/devices.  If "Driver=(none)", try forcing it  with	"modprobe
       scanner vendor=0x04a9 product=0x2204"

	      The backend configuration file (see also description of SANE_CONFIG_DIR below).

	      The static library implementing this backend.

	      The  shared  library  implementing  this	backend  (present on systems that support
	      dynamic loading).

	      The calibration file used to normalize pixel brightness.	This is calculated  every
	      time the scanner is first used after it has lost power.  It can be forced to recal-
	      ibrate by simply deleting this file.

	      This environment variable specifies the list of directories that	may  contain  the
	      configuration  file.   Under  UNIX, the directories are separated by a colon (`:'),
	      under OS/2, they are separated by a semi-colon (`;').  If this variable is not set,
	      the  configuration  file is searched in two default directories: first, the current
	      working directory (".") and then in /etc/sane.d.	If the value of  the  environment
	      variable	ends with the directory separator character, then the default directories
	      are searched after the explicitly  specified  directories.   For	example,  setting
	      SANE_CONFIG_DIR  to  "/tmp/config:"  would result in directories "tmp/config", ".",
	      and "/etc/sane.d" being searched (in this order).

	      If the library was compiled with debug support enabled, this  environment  variable
	      controls	the  debug level for this backend.  Higher debug levels increase the ver-
	      bosity of the output.

	      Example: export SANE_DEBUG_CANON630U=10
