Q:
Mbox 2 is not recognized by Pro Tools LE 7.
 
A:
Mbox 2 devices that have been updated with newer firmware to counteract an Apple PowerBook G4 compatibility issue may not be recognized by Pro tools 7.0 software. In this RARE case please install a newer "beta" Mbox 2 driver that can be found in the "Unsupported Software" folder on your Pro Tools 7.0 installer CD.
