What does “NO USB” or “USB ERROR” mean on Yamaha Home Theater System?
- BbcampbellSep 23, 2025
If your Yamaha Home Theater System displays “NO USB” or “USB ERROR”, the USB device is not compatible, or this unit cannot supply enough power to the device for it to function properly. Turn this unit off and on again. Set this unit to standby, disconnect the USB storage device, and then reconnect it. Select the USB input source, and then connect the USB device. Select a different input source and select USB again. If the USB storage device came with its own power adapter, use it to power the USB storage device while connecting to this unit.
