Those symptoms and that error are the result of USB connection problems on your computer. To minimize connection problems there are a few guidelines:
- Use a USB port directly on the computer, not a USB hub.
- If you have a Windows desktop or tower computer that has USB ports on both the front and back use a port on the back (front ports are usually an unpowered internal hub).
- If your computer has both USB 2 and USB 3 ports use a USB 2 port.
- Disconnect any power-consuming or high data rate USB devices while updating or syncing. These are mostly USB hard drives that do not have a separate power supply, but to be safe disconnect everything except keyboard, mouse and the iPhone.
- Reboot your computer just before syncing or updating.
