The same (?) problem here. After loading FW 005, restart, Menu ... USB serial ports 1, QMX off - on, check if 'USB serial ports 1' --> device manager shows no related COM-port and no related audio device.
Is there a basic difference between the old style USB (until FW 003) and the new style? Also the audio is affected since FW 004 not only the COM-port. As far as I understand for audio no ghost endpoint is relevant. So what else is different?
?
