- Plug the device directly into a high-power USB 2.0 port on the computer. If possible, use a USB port on the back of the computer.
- Avoid plugging the device into a keyboard, display, or standalone hub. The USB ports on these accessories may be low-power or only offer USB 1.x connections.
- If you are using an accessory, remove the device from the dock and connect it to the computer using only the Apple USB to Dock Connector cable.
- If you have access to additional Apple USB to Dock Connector cables, try testing with another if the first one doesn't work.
- Restart your computer and device. To restart your device:
- Hold the power button until "slide to power off" appears. Slide to power off your device. When it is off, press the Sleep/Wake button to turn it back on.
- Disconnect all USB devices from your computer, except for your keyboard and mouse. Then reconnect the iOS device. If the issue is resolved, reconnect other USB devices, testing after each connection.
