+/** @file plustek.c
+ * @brief SANE backend for Plustek scanner
+ *
+ * Based on Kazuhiro Sasayama previous work on
+ * plustek.[ch] file from the SANE package.<br>
+ * Original code taken from sane-0.71<br>
+ * Copyright (C) 1997 Hypercore Software Design, Ltd.<br>
+ * Also based on the work done by Rick Bronson<br>
+ * Copyright (C) 2000-2007 Gerhard Jaeger <gerhard@gjaeger.de><br>
+ *
+ * History:
+ * - 0.30 - initial version
+ * - 0.31 - no changes
+ * - 0.32 - no changes
+ * - 0.33 - no changes
+ * - 0.34 - moved some definitions and typedefs to plustek.h
+ * - 0.35 - removed Y-correction for 12000P model<br>
+ * - getting Y-size of scan area from driver
+ * - 0.36 - disabled Dropout, as this does currently not work<br>
+ * - enabled Halftone selection only for Halftone-mode<br>
+ * - made the cancel button work by using a child process during read<br>
+ * - added version code to driver interface<br>
+ * - cleaned up the code<br>
+ * - fixed sane compatibility problems<br>
+ * - added multiple device support<br>
+ * - 12bit color-depth are now available for scanimage
+ * - 0.37 - removed X/Y autocorrection, now correcting the stuff
+ * before scanning
+ * - applied Michaels' patch to solve the sane_get_parameter problem<br>
+ * - getting X-size of scan area from driver<br>
+ * - applied Michaels patch for OPT_RESOLUTION (SANE_INFO_INEXACT stuff)
+ * - 0.38 - now using the information from the driver
+ * - some minor fixes<br>
+ * - removed dropout stuff<br>
+ * - removed some warning conditions
+ * - 0.39 - added stuff to use the backend completely in user mode<br>
+ * - fixed a potential buffer problem<br>
+ * - removed function attach_one()<br>
+ * - added USB interface stuff
+ * - 0.40 - USB scanning works now
+ * - 0.41 - added some configuration stuff and also changed .conf file<br>
+ * - added call to sanei_usb_init() and sanei_lm983x_init()
+ * - 0.42 - added adjustment stuff<br>
+ * - added custom gamma tables<br>
+ * - fixed a problem with the "size-sliders"<br>
+ * - fixed a bug that causes segfault when using the autodetection for
+ * USB devices<br>
+ * - added OS/2 switch to disable the USB stuff for OS/2
+ * - 0.43 - added support for PREVIEW flag
+ * - 0.44 - added _DBG_DUMP debug level<br>
+ * - fixed a bug, that stops our lamp timer
+ * - 0.45 - added additional flags
+ * - added WIFSIGNALED to check result of child termination
+ * - changed readImage interface for USB devices
+ * - homeing of USB scanner is now working correctly
+ * - 0.46 - added plustek-usbcal.c for extra CIS device calibration
+ * based on Montys' great work
+ * - added altCalibration option
+ * - removed parallelport support --> new backend: plustek_pp
+ * - cleanup
+ * - added sanei_thread support
+ * - 0.47 - added mov-option (model override)
+ * - removed drvOpen
+ * - added call to usb_StartLampTimer, when we're using
+ * SIGALRM for lamp timer
+ * - closing now writer pipe, when reader_process is done
+ * - 0.48 - added additional options
+ * split scanmode and bit-depth
+ * - 0.49 - improved multi-device capability
+ * - tweaked some device settings
+ * - added button support
+ * - moved AFE stuff to enhanced options
+ * - 0.50 - cleanup
+ * - activated IPC stuff
+ * - added _DBG_DCALDATA for fine calibration data logging
+ * - added OPT_SPEEDUP handling
+ * - fixed constraint_type for OPT_BUTTON
+ * - 0.51 - added fine calibration caching
+ * - removed #define _PLUSTEK_USB
+ * - 0.52 - added skipDarkStrip and OPT_LOFF4DARK to frontend options
