NAME
sane-mustek_usb - SANE backend for Mustek USB flatbed scanners
DESCRIPTION
The sane-mustek_usb 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/mustek_usb-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 mustek_usb.conf file is a list of 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
mustek_usb.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, 1200cu_plus, 1200ub. For the Trust Compact
Scan USB 19200 use `option 1200ub'.
Instead of using the device name, the scanner can be autodetected by usb
vendor_id product_id statements which are already included into
mustek_usb.conf. This is only supported with Linux 2.4.8 and higher and
all systems that support libsub. "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
mustek_usb.conf as described above.
The global option max_block_size 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 /dev/usb/scanner0 and the fifth line
specifies that /dev/usb/scanner0 is a Mustek 600 CU.
FILES
/opt/local/etc/sane.d/mustek_usb.conf
The backend configuration file (see also description of
SANE_CONFIG_DIR below).
/opt/local/lib/sane/libsane-mustek_usb.a
The static library implementing this backend.
/opt/local/lib/sane/libsane-mustek_usb.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. 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
/opt/local/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
/opt/local/etc/sane.d being searched (in this order).
SANE_DEBUG_MUSTEK_USB
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.
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

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 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 appreciated.
