|
|
* - 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
