No it's PIC32. Nevertheless it does not matter - i wrote everything myself 
from scratch using only PIC32MX and USB documentation.

I am almost sure i didn't implement some of SCSI commands properly so 
FreeBSD doesn't properly behave, while windows/MacOS doesn't care.

The question is how to debug it on host side - what exactly is wrong.
