sane-mustek_usb - SANE backend for Mustek USB flatbed scanners
|
|
|
|
|
|
</PRE>
|
|
<H2>DESCRIPTION</H2><PRE>
|
|
The <B>sane-mustek_usb</B> library implements a SANE (Scanner Access Now Easy)
|
|
backend that provides access to Mustek USB flatbed scanners (including
|
|
a clone from Trust). At present, the following scanners are known to
|
|
work more or less with this backend:
|
|
|
|
Mustek 600 CU
|
|
Mustek 1200 UB
|
|
Mustek 1200 CU
|
|
Mustek 1200 CU Plus
|
|
Trust Compact Scan USB 19200
|
|
|
|
More details can be found on the Mustek USB backend homepage
|
|
<I>http://www.meier-geinitz.de/sane/mustek</I><B>_</B><I>usb-backend/</I>.
|
|
|
|
The Mustek BearPaw 1200 and 2400 scanners are supported by the plustek
|
|
backend. See <B><A HREF="sane-plustek.5.html">sane-plustek(5)</A></B> for details. The Mustek BearPaw 1200F is
|
|
supported by the MA-1509 backend. See <B><A HREF="sane-ma1509.5.html">sane-ma1509(5)</A></B> for details. Other
|
|
Mustek USB scanners are supported by the gt68xx backend, see
|
|
<B><A HREF="sane-gt68xx.5.html">sane-gt68xx(5)</A></B>.
|
|
|
|
This backend can only work with scanners that are already detected by
|
|
the operating system. See <B><A HREF="sane-usb.5.html">sane-usb(5)</A></B> for details.
|
|
|
|
If you own a Mustek (or Trust) 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
|
|
<I>/proc/bus/usb/devices</I> or syslog) to me.
|
|
|
|
|
|
</PRE>
|
|
<H2>DEVICE NAMES</H2><PRE>
|
|
This backend expects device names of the form:
|
|
|
|
<I>special</I>
|
|
|
|
Where <I>special</I> is a path-name for the special device that corresponds to
|
|
a USB scanner. With Linux, such a device name could be <I>/dev/usb/scan-</I>
|
|
<I>ner0</I> or <I>/dev/usbscanner1</I>, for example.
|
|
|
|
For FreeBSD use <I>/dev/uscanner0</I>.
|
|
|
|
|
|
</PRE>
|
|
<H2>CONFIGURATION</H2><PRE>
|
|
The contents of the <I>mustek</I><B>_</B><I>usb.conf</I> file is a list of options and de-
|
|
vice names that correspond to Mustek USB scanners. Empty lines and
|
|
lines starting with a hash mark (#) are ignored. If a device name is
|
|
placed in <I>mustek</I><B>_</B><I>usb.conf</I>, it must be followed by a line containing the
|
|
keyword <B>option</B> and an option specifying the scanner type. The following
|
|
options can be used: <B>600cu</B>, <B>1200cu</B>, <B>1200cu_plus</B>, <B>1200ub</B>. For the Trust
|
|
Compact Scan USB 19200 use `option 1200ub'.
|
|
|
|
Instead of using the device name, the scanner can be autodetected by
|
|
<B>usb</B> <B>vendor_id</B> <B>product_id</B> statements which are already included into
|
|
<I>mustek</I><B>_</B><I>usb.conf</I>. This is only supported with Linux 2.4.8 and higher
|
|
and all systems that support libusb. "vendor_id" and "product_id" are
|
|
hexadecimal numbers that identify the scanner. If this doesn't work, a
|
|
device name and the option specifying the scanner type must be placed
|
|
in <I>mustek</I><B>_</B><I>usb.conf</I> as described above.
|
|
|
|
The global <B>option</B> <B>max_block_size</B> can be used to limit the amount of
|
|
data acquired in one turn from the USB system. It may be worth trying,
|
|
if USB errors occur.
|
|
|
|
A sample configuration file is shown below:
|
|
|
|
# Comment
|
|
option max_block_size 1024
|
|
usb 0x055f 0x0001
|
|
/dev/usb/scanner0
|
|
option 600cu
|
|
|
|
The first line is ignored. The second line sets the buffer size to a
|
|
maximum of 1024 bytes. The third line tries to autodetect a scanner
|
|
with vendor id 0x055f and product id 0x0001 (Mustek 1200 CU). The
|
|
fourth line tells the backend to attach to <I>/dev/usb/scanner0</I> and the
|
|
fifth line specifies that <I>/dev/usb/scanner0</I> is a Mustek 600 CU.

<H2>FILES</H2><PRE>
|
|
<I>/usr/local/etc/sane.d/mustek</I><B>_</B><I>usb.conf</I>
|
|
The backend configuration file (see also description of
|
|
<B>SANE_CONFIG_DIR</B> below).
|
|
|
|
<I>/usr/local/lib/sane/libsane-mustek</I><B>_</B><I>usb.a</I>
|
|
The static library implementing this backend.
|
|
|
|
<I>/usr/local/lib/sane/libsane-mustek</I><B>_</B><I>usb.so</I>
|
|
The shared library implementing this backend (present on systems
|
|
that support dynamic loading).
|
|
|
|
|
|
</PRE>
|
|
<H2>ENVIRONMENT</H2><PRE>
|
|
<B>SANE_CONFIG_DIR</B>
|
|
This environment variable specifies the list of directories that
|
|
may contain the configuration file. On *NIX systems, the direc-
|
|
tories are separated by a colon (`:'), under OS/2, they are sep-
|
|
arated 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 <I>/usr/lo-</I>
|
|
<I>cal/etc/sane.d</I>. If the value of the environment variable ends
|
|
with the directory separator character, then the default direc-
|
|
tories are searched after the explicitly specified directories.
|
|
For example, setting <B>SANE_CONFIG_DIR</B> to "/tmp/config:" would re-
|
|
sult in directories <I>tmp/config</I>, <I>.</I>, and <I>/usr/local/etc/sane.d</I> be-
|
|
ing searched (in this order).
|
|
|
|
<B>SANE_DEBUG_MUSTEK_USB</B>
|
|
If the library was compiled with debug support enabled, this en-
|
|
vironment variable controls the debug level for this backend.
|
|
Higher debug levels increase the verbosity of the output.
|
|
|
|
Value Description
|
|
0 no output
|
|
1 print fatal errors
|
|
2 print important messages
|
|
3 print non-fatal errors and less important messages
|
|
4 print all but debugging messages
|
|
5 print high level debugging messages
|
|
6 print medium level debugging messages
|
|
7 print low level debugging messages
|
|
|
|
Example: export SANE_DEBUG_MUSTEK_USB=4

<H2>BUGS</H2><PRE>
|
|
These devices have a hardware bug: Once data is written to them, they
|
|
can't be reset (toggle = DATA0). That means, any operation that tries
|
|
to reset the device will result in running into timeouts.
|
|
|
|
In earlier versions this backend failed when it was loaded the second
|
|
time in some configurations. The only choice was to replug the scanner
|
|
in this case. The backend uses a workaround for that bug now but it's
|
|
only tested on Linux. Reports for other operating systems are appreci-
|
|
ated.
|
|
|
|
More detailed bug information is available at the Mustek backend home-
|
|
