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 +.RE + +.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/lib64/sane/libsane\-gt68xx.a +The static library implementing this backend. +.TP +.I /usr/lib64/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.
