[sane-devel] lost with FUJITSU scanner M3096G

[David Anders]

Dirk,

this is the same issue i had when working with the fi-4220 and fi-4120. 
aparently fujitsu changes some of the window bits on different models. 
some models don't like have 00 values in certain registers even if the 
register isn't used. have a look at roncemers fi-4120/4220 patches.


thanks
dave
