It looks as though your PS4 can’t detect a USB device. Make sure that your USB device is compatible and correctly configured by following the below steps:

  1. Verify that the USB device supports USB 2.0 or 3.0.
  2. Ensure the device is properly inserted in the PS4, and then wait for one minute before trying to access the device again.
  3. Make sure there are not multiple partitions on the device.
  4. Try reformatting the device using a PC if possible.
