Very common problem.
Are you sure you are using Made for Apple Cable? If so, you can try to update iTunes.
Ultimately, restore your device with TunesKit iOS System Recovery, which can restore your iDevices without data loss.

If encountered such errors while using iTunes, the easiest way to fix it is to put the iDevice into recovery mode and then connect to iTunes to restore it. Note that this method will wipe out all data on the device. Avoid losing data, just apply a repair tool like Joyoshare UltFix iOS system recovery. It can repair this kind of iOS issue without damaging any data. :D
