11  *
12  * History:
13  * - 0.40 - starting version of the USB support
14  * - 0.41 - added workaround flag to struct DevCaps
15  * - 0.42 - added MODEL_NOPLUSTEK
16  *        - replaced fLM9831 by chip (valid entries: _LM9831, _LM9832, _LM9833)
17  *        - added _WAF_MISC_IO3_LAMP for UMAX 3400
18  * - 0.43 - added _WAF_MISC_IOx_LAMP (x=1,2,4,5)
19  *        - added CLKDef
20  * - 0.44 - added vendor and product ID to struct DeviceDef

23  * - 0.45 - added _WAF_SKIP_FINE for skipping fine calibration
24  *        - added _WAF_SKIP_WHITEFINE for skipping fine white calibration
25  *        - added MCLK setting for 16 bit modes
26  *        - added _WAF_FIX_GAIN and _WAF_FIX_OFS

49  *        - changed DCapsDef, lamp -> misc_io
50  *        - bPCB is now ushort to be "missused" by non Plustek
51  *          devices (as threshold for resetting sensor order)
52  *        - added _WAF_LOFF_ON_START and _WAF_ONLY_8BIT
