I'm trying to setup my Alphatrack to work with ProTools MBox2(v.6.8.1 running on PowerBook Mac OS 10.3.9) and after performing install and plugging the device into USB ports (I tried both) the LCD lights up but in the Alphatrack manager the status bar says "Alphatrack Not Available". I have uninstalled driver and reinstalled driver with no success. I downloaded and installed the updated driver and no success. Am I missing something or is my device defective?
