SANE Scanner Access Now Easy sane-mustekusb(5)
NAME
sane-mustekusb - SANE backend for Mustek USB flatbed
scanners
DESCRIPTION
The sane-mustekusb 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
http:/www.meier-geinitz.de/sane/mustekusb-backend/.
The Mustek BearPaw 1200 and 2400 scanners are supported by
the plustek backend. See sane-plustek(5) for details. The
Mustek BearPaw 1200F is supported by the MA-1509 backend.
See sane-ma1509(5) for details. Other Mustek USB scanners
are supported by the gt68xx backend, see sane-gt68xx(5).
This backend can only work with scanners that are already
detected by the operating system. See sane-usb(5) 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 /proc/bus/usb/devices
or syslog) to me.
DEVICE NAMES
This backend expects device names of the form:
special
Where special is a path-name for the special device that
corresponds to a USB scanner. With Linux, such a device
name could be /dev/usb/scanner0 or /dev/usbscanner1, for
example.
For FreeBSD use /dev/uscanner0.
CONFIGURATION
The contents of the mustekusb.conf file is a list of
sane-backends 1.0.19 Last change: 3 Mar 2004 1
SANE Scanner Access Now Easy sane-mustekusb(5)
options and device 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
mustekusb.conf, it must be followed by a line containing
the keyword option and an option specifying the scanner
type. The following options can be used: 600cu, 1200cu,
1200cuplus, 1200ub. For the Trust Compact Scan USB 19200
use `option 1200ub'.
Instead of using the device name, the scanner can be auto-
detected by usb vendorid productid statements which are
already included into mustekusb.conf. This is only sup-
ported with Linux 2.4.8 and higher and all systems that sup-
port libsub. "vendorid" and "productid" 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 mustekusb.conf as described above.
The global option maxblocksize 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 maxblocksize 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 /dev/usb/scanner0 and the fifth line specifies
that /dev/usb/scanner0 is a Mustek 600 CU.
FILES
/etc/sane.d/mustekusb.conf
The backend configuration file (see also description of
SANECONFIGDIR below).
/usr/lib/sane/libsane-mustekusb.a
The static library implementing this backend.
/usr/lib/sane/libsane-mustekusb.so
The shared library implementing this backend (present
on systems that support dynamic loading).
ENVIRONMENT
SANECONFIGDIR
This environment variable specifies the list of
sane-backends 1.0.19 Last change: 3 Mar 2004 2
SANE Scanner Access Now Easy sane-mustekusb(5)
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
SANECONFIGDIR to "/tmp/config:" would result in
directories "tmp/config", ".", and "/etc/sane.d" being
searched (in this order).
SANEDEBUGMUSTEKUSB
If the library was compiled with debug support enabled,
this environment variable controls the debug level for
this backend. Higher debug levels increase the verbos-
ity 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 SANEDEBUGMUSTEKUSB=4

This backend is based on the Mustek 1200ub backend from
Mustek, maintained by Tom Wang.
BUGS
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 run-
ning 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 wor-
karound for that bug now but it's only tested on Linux.
Reports for other operating systems are appreciated.
