/** @file plustek-usb.h
* @brief Main defines for the USB devices.
*
* Based on sources acquired from Plustek Inc.<br>
* Copyright (C) 2001-2007 Gerhard Jaeger <gerhard@gjaeger.de>
*
* History:
* - 0.40 - starting version of the USB support
* - 0.41 - added workaround flag to struct DevCaps
* - 0.42 - added MODEL_NOPLUSTEK
* - replaced fLM9831 by chip (valid entries: _LM9831, _LM9832, _LM9833)
* - added _WAF_MISC_IO3_LAMP for UMAX 3400
* - 0.43 - added _WAF_MISC_IOx_LAMP (x=1,2,4,5)
* - added CLKDef
* - 0.44 - added vendor and product ID to struct DeviceDef
* - added _WAF_BYPASS_CALIBRATION
* - added _WAF_INV_NEGATIVE_MAP
* - 0.45 - added _WAF_SKIP_FINE for skipping fine calibration
* - added _WAF_SKIP_WHITEFINE for skipping fine white calibration
* - added MCLK setting for 16 bit modes
* - added _WAF_FIX_GAIN and _WAF_FIX_OFS
* - 0.46 - added UMAX1200 for 5400 model
* - removed _WAF_FIX_GAIN and _WAF_FIX_OFS
* - added skipCoarseCalib to ScanDef
* - added additional defines for cis and epson-ccd sensor
* - 0.47 - cleanup work
* - added gamma to struct HWDefault
* - 0.48 - added DEVCAPSFLAG_LargeTPA
* - added _WAF_BIN_FROM_COLOR and _WAF_GRAY_FROM_COLOR
* - added dHighSpeed to struct HwDefault
* - 0.49 - added a_bRegs, fModFirstHome and fLastScanIsAdf
* to struct DeviceDef
* - added CRYSTAL_FREQ
* - added IPCDef
* - 0.50 - cleanup
* - removed obsolete _WAF_BLACKFINE
* - added MODEL_CANON_LIDE25
* - 0.51 - added _WAF_MISC_IO_BUTTONS plus _BUTTON stuff
* - added _WAF_USE_ALT_DESC
* - added DEVCAPSFLAG_SheetFed
* - added dpi_thresh and lineend to motor structure
* - 0.52 - added MODEL_QSCAN
* - changed DCapsDef, lamp -> misc_io
* - bPCB is now ushort to be "missused" by non Plustek
* devices (as threshhold for resetting sensor order)
* - added _WAF_LOFF_ON_START and _WAF_ONLY_8BIT
* - added MODEL_TSCAN_A4
* - added attribute packed for data access structs
* - added _WAF_INC_DARKTGT
