Solution 3: make sure the USB Cable Connection
The USB cable can be damaged, if you happen to use a cable that does not come with your device. The following steps to make sure the USB cable is fine.
- Make sure the original USB cable is used. You can also try the standard Apple USB cable.
- Make sure the cables are not detached or revoked. You may get an error 9006 iPhone too.
- Plug the cable into the USB port of the other. This must be connected directly to the computer and not the keyboard.
