[Karsten Festag]

Hi Michael,
I'm afraid we misunderstood each other. I don't need the scsi data when 
scanning with SANE. What I need is the SCSI data of the windows driver 
and I did this for my scanner with the windows emulator 'wine' 
(www.winehq.com). I installed a windows scanning program (IrfanView) 
and the Microtek Scanwizard for windows using this 'wine. Wine is able 
to log the data that are send between scanner and computer.  

Regards,

Karsten
