6 sane-genesys - SANE backend for GL646 and GL841 based USB flatbed scan‐
7 ners
8
10 The sane-genesys library implements a SANE (Scanner Access Now Easy)
11 backend that provides access to USB flatbed scanners based on the
12 Genesys GL646 and GL841 chips. At present, the following scanners are
13 known to work with this backend:
14 Medion MD6228
16 Medion MD6274
17 Hewlett-Packard HP2300C
18 Canon LiDE 35/40/50/60
19 This is BETA software. Especially if you test new or untested scanners,
22 keep your hand at the scanner's plug and unplug it, if the head bumps
23 at the end of the scan area.
24 If you own a scanner other than the ones listed above that works with
26 this backend, please let me know this by sending the scanner's exact
27 model name and the USB vendor and device ids (e.g. from
28 /proc/bus/usb/devices , sane-find-scanner or syslog) to the sane-devel
29 mailing list. Even if the scanner's name is only slightly different
30 from the models mentioned above, please let me know.
31 If you own a scanner that isn't detected by the genesys backend but has
33 a GL646 or GL841 chipset, you can try to add it to the backend.
34
36 This backend needs libusb-0.1.6 or later installed, and hasn't tested
37 in other configuration than a linux kernel 2.6.9 or higher. However, it
38 should work any system with libusb where the SANE package can be com‐
39 piled. For setting permissions and general USB information look at
40 sane-usb(5).
41
45 The contents of the genesys.conf file is a list of usb lines containing
46 vendor and product ids that correspond to USB scanners. The file can
47 also contain option lines. Empty lines and lines starting with a hash
48 mark (#) are ignored. The scanners are autodetected by usb vendor_id
49 product_id statements which are already included into genesys.conf.
50 "vendor_id" and "product_id" are hexadecimal numbers that identify the
51 scanner.
52
54 /etc/sane.d/genesys.conf
55 The backend configuration file (see also description of
56 SANE_CONFIG_DIR below).
57 /usr/lib*/sane/libsane-genesys.a
59 The static library implementing this backend.
60 /usr/lib*/sane/libsane-genesys.so
62 The shared library implementing this backend (present on systems
63 that support dynamic loading).
64
66 SANE_CONFIG_DIR
67 This environment variable specifies the list of directories that
68 may contain the configuration file. Under UNIX, the directories
69 are separated by a colon (`:'), under OS/2, they are separated
70 by a semi-colon (`;'). If this variable is not set, the config‐
71 uration file is searched in two default directories: first, the
72 current working directory (".") and then in /etc/sane.d. If the
73 value of the environment variable ends with the directory sepa‐
74 rator character, then the default directories are searched after
75 the explicitly specified directories. For example, setting
76 SANE_CONFIG_DIR to "/tmp/config:" would result in directories
77 "tmp/config", ".", and "/etc/sane.d" being searched (in this
78 order).
79 SANE_DEBUG_GENESYS
81 If the library was compiled with debug support enabled, this
82 environment variable controls the debug level for this backend.
83 Higher debug levels increase the verbosity of the output. If the
84 debug level is set to 1 or higher, some debug options become
85 available that are normally hidden. Handle them with care. This
86 will print messages related to core genesys functions.
87 SANE_DEBUG_GENESYS_GL646
89 This environment variable controls the debug level for the spe‐
90 cific GL646 code part.
91 SANE_DEBUG_GENESYS_GL841
93 This environment variable controls the debug level for the spe‐
94 cific GL841 code part.
95 Example (full and highly verbose output for gl646):
98 export SANE_DEBUG_GENESYS=255
99 export SANE_DEBUG_GENESYS_GL646=255
