Are you using a OEM cable ? Aftermarket cables that are not MFI will charge your device but not allow it to Sync. 1. Reinstall iTunes & Drivers associated 2. Use a tooth pick & combo of a eyeglass cloth to clean out your charging port for any gunk. 3. Clean the port using 99% alcohol to ensure there are no corrosion causing a jump Good luck.
