SCSI command expert needed :)

[Wojciech Puchar]

i already got help from this list (thank you again) as i am implementing 
USB-CD emulating functionality on microcontroler hardware with USB 
connection.

Actually - i already implemented it.

Works with FreeBSD
Works with windows XP,7,8,10
Works with linux

Doesn't work with Mac OS X.

To make thing more fun - i attached REAL USB DVD recorder to Mac OS X and 
doesn't work too.

To be exact - message window "CD is unreadable" appears.

But i DO NEED my product to work with Mac OS X.

I already have some ideas where is a problem but if someone could help - 
please mail me.
