Why does my Yamaha RX-V3900 say 'No Device' when a USB is plugged in?

If “No Device” is displayed even when a USB device is connected to your Yamaha Receiver, the unit may have recognized the USB storage device as an illegal device. Try turning the unit off and then on again. Also, ensure that music files and directories are placed in the FAT area of the USB device.
