/* @file plustek-pp_motor.c
* @brief all functions for motor control
*
* based on sources acquired from Plustek Inc.
* Copyright (C) 1998 Plustek Inc.
* Copyright (C) 2000-2004 Gerhard Jaeger <gerhard@gjaeger.de>
* also based on the work done by Rick Bronson
*
* History:
* - 0.30 - initial version
* - 0.31 - no changes
* - 0.32 - slight cosmetic changes
* - added function MotorToHomePosition()
* - 0.33 - added additional debug-messages
* - increased speed for returning to homeposition for Models >= 9630
* (and ASIC 96003)
* - 0.34 - added FIFO overflow check in motorP96SetSpeed
* - removed WaitBack() function from pScanData structure
* - removed wStayMaxStep from pScanData structure
* - 0.35 - changed motorP96UpdateDataCurrentReadLine() to handle proper
* - work of ASIC96003 based 600dpi models
* - 0.36 - merged motorP96WaitBack and motorP98WaitBack to motorWaitBack
* - merged motorP96SetSpeed and motorP98SetSpedd to motorSetSpeed
* - added Sensor-Check in function MotorToHomePosition
* - reduced number of forward steps for MotorToHomePosition
* - 0.37 - removed function motorP96GetStartStopGap() - no longer used
* - removed a_bStepDown1Table and a_bStepUp1Table
* - removed // comments
* - added A3I stuff
* - 0.38 - cosmetic changes
* - added P12 stuff
* - 0.39 - Did some finetuning in MotorP98003ModuleForwardBackward()
* - Fixed a problem, that could cause the driver to throw a
* kernel exception
* - 0.40 - changed back to build 0.39-3 (disabled A3I stuff)
* - 0.41 - no changes
* - 0.42 - changed include names
* - 0.43 - no changes
* .
