Unknown error 9 ipod touch, iphone, itunes

Error 9:

This error occurs when the device unexpectedly drops off of the USB bus and communication stops.

This can occur if the device is manually disconnected during the restore process.

This issue can be resolved by performing USB isolation troubleshooting, using a different USB dock connector cable, trying another USB port, (DO NOT USE HUBS) restoring on another computer, or by eliminating conflicts from third-party security software.

When uploading the audio files from any folder


Why don’t you try another usb cable? Or you could try transferring via Bluetooth as well. From the message, 'unexpected error has occurred in communication' you can see that the device providing the communication between phone and PC, i.e. cable is not functioning well. That is why even when you switch from port to port the problem persists.
