I had the same problem with the plustek backend; IMHO the assumption, that a 
call to sane_control_option() must return SANE_STATUS_INVAL if the option is 
inactive, is simply wrong. I also don't see a reason, why one should change 
code, that (as far as I can tell) works without problems with every frontend 
I've tested.
At the moment, it's tstbackend that needs some bug fixes/improvements :-)
