+.SH NAME
+sane\-gt68xx \- SANE backend for GT-68XX based USB flatbed scanners
+.SH DESCRIPTION
+The
+.B sane\-gt68xx
+library implements a SANE (Scanner Access Now Easy) backend that provides
+access to USB flatbed scanners based on the Grandtech GT-6801 and GT-6816
+chips.  A list of supported scanners can be found on the gt68xx backend
+homepage:
+.IR http://www.meier\-geinitz.de/sane/gt68xx\-backend/ .
+.PP
+This is BETA software. Especially if you test new or untested scanners, keep
+your hand at the scanner's plug and unplug it, if the head bumps at the end of
+the scan area.
+.PP
+If you own a scanner other than the ones listed on the gt68xx homepage that works with this
+backend, please let me know this by sending the scanner's exact model name and
+the USB vendor and device ids (e.g. from
+.BR sane\-find\-scanner (1)
+or syslog) to me. Even if the scanner's name is only slightly different from
+the models already listed as supported, please let me know.
+.PP
+If you own a scanner that isn't detected by the gt68xx backend but has a GT-6801
+or GT-6816 chipset, you can try to add it to the backend. Have a look at the
+following web page:
+.I http://www.meier\-geinitz.de/sane/gt68xx\-backend/adding.html
+.PP
+.SH LIBUSB ISSUES
+Please use libusb-0.1.8 or later. Without libusb or with older libusb versions
+all kinds of trouble can be expected. The scanner should be found by
+.BR sane\-find\-scanner (1)
+without further actions. For setting permissions and general USB information, look at
+.BR sane\-usb (5).
+.PP
+
+.SH FIRMWARE FILE
+You need a firmware file for your scanner. That's a small file containing
+software that will be uploaded to the scanner's memory. It's usually named
+*.usb, e.g.
+.IR PS1fw.usb .
+It comes on the installation CD that was provided by the manufacturer, but it
+may be packaged together with the installation program in an .exe file. For
+Mustek scanners, the file can be downloaded from the gt68xx backend homepage. For
+other scanners, check the CD for .usb files. If you only find *.cab files, try
+.BR cabextract (1)
+to unpack. If everything else fails, you must install the Windows
+driver and get the firmware from there (usually in the
+.I windows/system
+or
+.I system32
+directories). Put that firmware file into
+.IR /usr/share/sane/gt68xx/ .
+Make sure that it's readable by everyone.
+
+.SH CONFIGURATION
+The contents of the
+.I gt68xx.conf
+file is a list of usb lines containing vendor and product ids that correspond
+to USB scanners. The file can also contain option lines.  Empty lines and
+lines starting with a hash mark (#) are ignored.  The scanners are
+autodetected by
+.B usb vendor_id product_id
+statements which are already included into
+.IR gt68xx.conf .
+"vendor_id" and "product_id" are hexadecimal numbers that identify the
+scanner.
+.PP
+The
+.BR override ,
+.BR firmware ,
+.BR vendor ,
+.BR model ,
+and
+.B afe
+options must be placed after the
+.B usb
+line they refer to.
+.PP
+Option
+.B override
+is used to override the default model parameters. That's necessary for some
+scanners that use the same vendor/product ids but are different. For these
+scanners there are already commented out override lines in the configuration
+file.
+.B override "mustek\-scanexpress\-1200\-ub\-plus"
+is necessary for the Mustek Scanexpress 1200 UB Plus, the
+Medion/Lifetec/Tevion LT 9452, and the Trust Compact Scan USB 19200.
+.B override "artec\-ultima\-2000"
+is used for the Artec Ultima 2000, the Boeder SmartScan Slim Edition, the
+Medion/ Lifetec/ Tevion/ Cytron MD/LT 9385, the Medion/ Lifetec/ Tevion MD
+9458, and the Trust Flat Scan USB 19200.
+.B override "mustek\-bearpaw\-2400\-cu"
+is necessary for the Mustek BearPaw 2400 CU and the Fujitsu 1200CUS. The
+.B override
+option must be the first one after the
+.B usb
+line.
+.PP
+Option
+.B firmware
+selects the name and path of the firmware file. It's only necessary if the
+default (or override) doesn't work. The default firmware directory is
+.IR /usr/share/sane/gt68xx/ .
+You may need to create this directory. If you want to place the firmware files
+at a different path, use a
+.B firmware
+line.
+.PP
+The
+.B vendor
+and
+.B model
+options are not absolutely necessary but for convenience. Quite a lot of
+scanners from different manufacturers share the same vendor/product ids so you
+can set the "correct" name here.
+.PP
+The
+.B afe
+option allows one to set custom offset and gain values for the Analog FrontEnd of
+the scanner. This option can be either used to select the AFE values if
+automatic coarse calibration is disabled, or to make automatic coarse
+calibration faster. For the latter usage, enable debug level 3 (see below),
+scan an image and look for debug line string with "afe". Copy this line to
+.IR gt68xx.conf .
+The option has six parameters: red offset, red gain, green offset, green gain,
+blue offset, and blue gain.
+.PP
+A sample configuration file is shown below:
+.PP
+.RS
+usb 0x05d8 0x4002
+.br
+override "mustek\-scanexpress\-1200\-ub\-plus"
+.br
+firmware "/opt/gt68xx/SBfw.usb"
+.br
+vendor "Trust"
+.br
+model "Compact Scan USB 19200"
+.br
+afe 0x20 0x02 0x22 0x03 0x1f 0x04

+.SH FILES
+.TP
+.I /etc/sane.d/gt68xx.conf
+The backend configuration file (see also description of
+.B SANE_CONFIG_DIR
+below).
+.TP
+.I /usr/lib/sane/libsane\-gt68xx.a
+The static library implementing this backend.
+.TP
+.I /usr/lib/sane/libsane\-gt68xx.so
+The shared library implementing this backend (present on systems that
+support dynamic loading).
+.SH ENVIRONMENT
+.TP
+.B SANE_CONFIG_DIR
+This environment variable specifies the list of directories that may
+contain the configuration file.  On *NIX systems, 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
+.IR /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
+.B SANE_CONFIG_DIR
+to "/tmp/config:" would result in directories
+.IR tmp/config ,
+.IR . ,
+and
+.I "/etc/sane.d"
+being searched (in this order).
+.TP
+.B SANE_DEBUG_GT68XX
+If the library was compiled with debug support enabled, this environment
+variable controls the debug level for this backend.  Higher debug levels
+increase the verbosity of the output. If the debug level is set to 1 or higher,
+some debug options become available that are normally hidden. Handle them with
+care.
+
+Example:
+export SANE_DEBUG_GT68XX=4

+David Stevenson. Thanks for sending patches and answering questions to them
+and all the other contributors.
+
+.SH BUGS
+The first few lines of the image are garbage for the 2400 TA
+Plus.
+.PP
+Interpolation should be used instead of just copying data, when the X- and
+Y-resolution differ.
+.PP
+Support for buttons is missing.
+.PP
+More detailed bug information is available at the gt68xx backend homepage
+.IR http://www.meier\-geinitz.de/sane/gt68xx\-backend/ .
