hello,

thanks for your help - still not working.

extracted
cism216.fw
and
cism603.fw

from the windows driver. Renamed it to *.usb abd copied to
/usr/share/sane/gt68xx>
With the cism216.usb the scanner does not react.
With cism603.usb the scanner scans - but as described only a grey page.

I saw the manpage and found the afe configuration accordingly - but it 
still has the same result.

I set the afe in the gt68xx.conf according to the output witg debug level 3.
