I have tried everything and cannot get my newer hp laptop with Windows 7 to recognize the AR16 USB mixer. I know the cable is good, windows has the most recent update, the USB drivers are all updated. I have reinstalled, tried everything obvious and read everything online that there is about this. I cannot get a signal from the mixer to my laptop and I dont understand why. The only explanation I can think of is the USB port is defective on the mixer. Anyone else have this problem? I have uninstalled and reinstalled Universal control over and over. Nothing works.
