sane-hp5400 - SANE backend for Hewlett-Packard 54XX scanners

The sane-hp5400 library implements a SANE (Scanner Access Now Easy) backend that provides access to the following Hewlett-Packard USB flatbed scanners:

ScanJet 5400C

ScanJet 5470C

ScanJet 5490C

More details can be found on the hp5400 backend homepage http://hp5400backend.sourceforge.net/.

This is ALPHA software. Keep your hand at the scanner's plug and unplug it, if the head bumps at the end of the scan area. See also the BUGS section.

If you own a scanner other than the ones listed above that works with this backend, please let us know this by sending the scanner's exact model name and the USB vendor and device ids (e.g. from /proc/bus/usb/devices, sane-find-scanner or syslog) to us. Even if the scanner's name is only slightly different from the models mentioned above, please let us know.

The contents of the hp5400.conf file is a list of usb lines containing vendor and product ids that correspond to USB scanners. The file can also contain the names of device files that correspond to an HP 54XX scanner. Empty lines and lines starting with a hash mark (#) are ignored. The scanners are autodetected by usb vendor_id product_id statements which are already included into hp5400.conf. "vendor_id" and "product_id" are hexadecimal numbers that identify the scanner. If autodetection does not work, add the device name of your scanner to the configuration file, e.g. /dev/usb/scanner0.

/etc/sane.d/hp5400.conf

The backend configuration file (see also description of SANE_CONFIG_DIR below).

/usr/lib/sane/libsane-hp5400.a

The static library implementing this backend.

/usr/lib/sane/libsane-hp5400.so

The shared library implementing this backend (present on systems that support dynamic loading).

SANE_CONFIG_DIR

This environment variable specifies the list of 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 SANE_CONFIG_DIR to "/tmp/config:" would result in directories "tmp/config", ".", and "/etc/sane.d" being searched (in this order).

SANE_DEBUG_HP5400

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_HP5400=4

Scanning is only tested with Linux/ix86/gcc. Be careful when testing on other operating systems and especially on big-endian platforms. The scanner may get wrong data.
