Media 100i & Tiger & Stealth

Has anyone using Media 100i upgraded to Tiger? When using Media 100i, I am unable to use deck control. An error pops up that says thois machine does not have serial ports. Does anyone know if there's an update for Stealth Serial Port adaptor? Is there a USB to Serial adapter that I can use? Should I just go back to Panther? I could really use some help.

Thanks,
Gabe
