NAME
sane-genesys - SANE backend for GL646 and GL841 based USB flatbed scanners
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:
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 compiled. 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
/etc/sane.d/genesys.conf
The backend configuration file (see also description of
SANE_CONFIG_DIR
below).
/usr/lib/sane/libsane-genesys.a
The static library implementing this backend.
/usr/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 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).
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 specific GL646 code
part.
SANE_DEBUG_GENESYS_GL841
This environment variable controls the debug level for the specific GL841 code
part.
Example (full and highly verbose output for gl646):
export SANE_DEBUG_GENESYS=255
export SANE_DEBUG_GENESYS_GL646=255
