Thanks for confirmation, I thought it was just AES3500 performs badly.
Is it the matching approach (i.e. minuates detection and matching in NBIS)
that poses a limitation on verification of these kind devices?
Is the Windows driver using a completely different approach on verification?
Sorry, my experiences are very limited, would very much like to get your
