Thank you very much for help. Already with your help i made everything working on microcontroller side as i wanted - emulation of USB CD drive + few "vendor specific" (>=0xC0) SCSI commands for my needs. Tiny, fast and no messy ready to use libraries. As it's quite off topic i propose to close that topic. But i asked freebsd-hackers for simple reason to get help from people knowing USB and SCSI specifics. And got it. Thank you very much.
