sane-genesys(5) SANE Scanner Access Now Easy sane-genesys(5)NAMEsane-genesys - SANE backend for GL646 and GL841 based USB flatbed scan‐
ners
DESCRIPTION
The sane-genesys library implements a SANE (Scanner Access Now Easy)
backend that provides access to USB flatbed scanners based on the
Genesys GL646 and GL841 chips. At present, the following scanners are
known to work with this backend:
Medion MD6228
Medion MD6274
Hewlett-Packard HP2300C
Canon LiDE 35/40/50/60
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.
If you own a scanner other than the ones listed above 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
/proc/bus/usb/devices , sane-find-scanner or syslog) to the sane-devel
mailing list. Even if the scanner's name is only slightly different
from the models mentioned above, please let me know.
If you own a scanner that isn't detected by the genesys backend but has
a GL646 or GL841 chipset, you can try to add it to the backend.
SYSTEM ISSUES
This backend needs libusb-0.1.6 or later installed, and hasn't tested
in other configuration than a linux kernel 2.6.9 or higher. However, it
should work any system with libusb where the SANE package can be com‐
piled. For setting permissions and general USB information look at
sane-usb(5).
CONFIGURATION
The contents of the genesys.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 usb vendor_id
product_id statements which are already included into genesys.conf.
"vendor_id" and "product_id" are hexadecimal numbers that identify the
scanner.
FILES
/system/resources/sane-backends/1.0.18/etc/sane.d/genesys.conf
The backend configuration file (see also description of
SANE_CONFIG_DIR below).
/system/resources/sane-backends/1.0.18/lib/sane/libsane-genesys.a
The static library implementing this backend.
/system/resources/sane-backends/1.0.18/lib/sane/libsane-genesys.so
The shared library implementing this backend (present on systems
that support dynamic loading).
ENVIRONMENT
SANE_CONFIG_DIR
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 config‐
uration file is searched in two default directories: first, the
current working directory (".") and then in /sys‐
tem/resources/sane-backends/1.0.18/etc/sane.d. If the value of
the environment variable ends with the directory separator char‐
acter, 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 "/system/resources/sane-back‐
ends/1.0.18/etc/sane.d" being searched (in this order).
SANE_DEBUG_GENESYS
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. This
will print messages related to core genesys functions.
SANE_DEBUG_GENESYS_GL646
This environment variable controls the debug level for the spe‐
cific GL646 code part.
SANE_DEBUG_GENESYS_GL841
This environment variable controls the debug level for the spe‐
cific GL841 code part.
Example (full and highly verbose output for gl646):
export SANE_DEBUG_GENESYS=255
export SANE_DEBUG_GENESYS_GL646=255
