.SH NAME
|
|
sane\-u12 \- SANE backend for Plustek USB flatbed scanners,
|
|
based on older parport designs
|
|
.SH DESCRIPTION
|
|
The
|
|
.B sane\-u12
|
|
library implements a SANE (Scanner Access Now Easy) backend that
|
|
provides access to USB flatbed scanners based on Plusteks' ASIC
|
|
98003 (parallel-port ASIC) and a GeneSys Logics' USB-parport
|
|
bridge chip.
|
|
|
|
.SH "SUPPORTED DEVICES"
|
|
The backend is able to support some early Plustek USB scanners that based
|
|
their old parport design around the ASIC 98003 and other rebadged
|
|
Plustek devices. The following tables will give you a short overview.
|
|
|
|
If your Plustek scanner has another Product ID, then the device is
|
|
.B NOT
|
|
supported by this backend.

.SH "CONFIGURATION"
|
|
To use your scanner with this backend, you need at least two
|
|
entries in the configuration file
|
|
.I @CONFIGDIR@/u12.conf
|
|
|
|
.RS
|
|
.I [usb] vendor-id product-id
|
|
.br
|
|
.I device /dev/usbscanner
|
|
.RE
|
|
.PP
|
|
.I [usb]
|
|
tells the backend, that the following devicename (here
|
|
.IR /dev/usbscanner )
|
|
has to be interpreted as USB scanner device. If vendor- and
|
|
product-id has not been specified, the backend tries to
|
|
detect this by its own. If device is set to
|
|
.I auto
|
|
then the next matching device is used.
|
|
.PP
|
|
.B
|
|
The Options:
|
|
.PP
|
|
option warmup t
|
|
.RS
|
|
.I t
|
|
specifies the warmup period in seconds
|
|
.RE
|
|
.PP
|
|
option lampOff t
|
|
.RS
|
|
.I t
|
|
is the time in seconds for switching off the lamps in
|
|
standby mode
|
|
.RE
|
|
.PP
|
|
option lOffonEnd b
|
|
.RS
|
|
.I b
|
|
specifies the behaviour when closing the backend, 1 --> switch
|
|
lamps off, 0 --> do not change lamp status
|
|
.RE
|
|
|
|
.PP
|
|
See the
|
|
.I u12.conf
|
|
file for examples.
|
|
.PP
|
|
.B Note:
|
|
You have to make sure, that the USB subsystem is loaded
|
|
correctly and you have access to the device-node. For
|
|
more details see
|
|
.BR sane\-usb (5)
|
|
manpage. You might use
|
|
.BR sane\-find\-scanner (1)
|
|
to check that you have access to your device.
|
|
.PP
|
|
.B Note:
|
|
.br
|
|
If there's no configuration file, the backend defaults to
|
|
.B device auto
|
|
|
|
.SH FILES
|
|
.TP
|
|
.I @CONFIGDIR@/u12.conf
|
|
The backend configuration file
|
|
.TP
|
|
.I @LIBDIR@/libsane\-u12.a
|
|
The static library implementing this backend.
|
|
.TP
|
|
.I @LIBDIR@/libsane\-u12.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 @CONFIGDIR@ .
|
|
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 @CONFIGDIR@
|
|
being searched (in this order).
|
|
.TP
|
|
.B SANE_DEBUG_U12
|
|
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.
|
|
|
|
Example:
|
|
export SANE_DEBUG_U12=10

Please send any information and bug-reports to:

|
|
.B SANE Mailing List
|
|
.PP
|
|
Additional info and hints can be obtained from our mailing-List archive at:
|
|

|
.PP
|
|
To obtain debug messages from the backend, please set the
|
|
environment-variable
|
|
.B SANE_DEBUG_U12
|
|
before calling your favorite SANE frontend (e.g.
|
|
.BR xscanimage (1)):
|
|
.PP
|
|
.I export SANE_DEBUG_U12=20 ; xscanimage
|
|
.PP
|
|
The value controls the verbosity of the backend.
|
|
|
|
.SH "KNOWN BUGS & RESTRICTIONS"
|
|
* The driver is in alpha state, so please don't expect too much!!!
|
|
.PP
|
|
* When using libusb, it might be, that the backend hangs.
|
|
In that case, reconnect the scanner.
