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