He,he - don't put the blame on me ;)
Well - of course you might wan't to check that with the epkowa backend, you
might also want to tweak the gamma options in the plustek.conf file:
# for adjusting the default gamma values
# (can also be set via frontend)
option redGamma 1.5
option greenGamma 1.5
option blueGamma 1.5
option grayGamma 1.5
Default is 1.0 for this device, which means use a linear map, 1.5 should
increase the brightness.
Hope this helps.
