If your instrument is not running the most current firmware (Operating System), it may fail to recognize "state of the art" USB devices. To find the current firmware for your instrument:
1. Go to: usa.yamaha.com
2. Type your model # in the search field
3. Click on Support or Downloads
Compare the latest firmware (OS) with the OS that is in your instrument.
NOTE: Do not use "U3" USB flash drives. They are not compatible with Yamaha Products.
