I did, also changed sense_handler 
1. condition of first if to true (dev is only used and refernced in this if)
2. return GOOD if LAMP_Error

now the scanner is seen by scanimage -L - 
but it does not work - if I continue with Lamp error, I finally end up with a 
command sequence error.
this is the nice part of the output:

hmmm.
Windows asks for the film to be removed and does an initialization of the 
scanner on first use after reboot - may be, this is what it expects?

any ideas which command this would be?

yes, but at the end of it - and after the call to test_unit_ready - at least 
as I see it - which may be wrong. 

thx
