My salesman has a call going in to Yamaha to see what they suggest. Most likely, it's going back since the USB to HOST port recognizes NOTHING, no matter what you stick in there. I made sure it went in all the way. I reformatted. I rebooted, I did everything but stand on my head and spit wooden nickels! This thing is BROKE! I'm trying one more time. Surely lightning won't strike 3x
