Disconnect the Lightning to USB3 Camera Adapter from the iPad - and directly connect the Power Adapter’s USB cable to the Lightning connector of the iPad. Verify that the iPad is charging.
If the iPad shows that it is charging from the Power Adapter, whilst still connected to the Power Adapter, force restart the iPad:
- On an iPad with a Home button: Press and hold the top button and the Home button at the same time. When the Apple logo appears, release both buttons.
- On other iPad models: Press and quickly release the volume up button, press and quickly release the volume down button, then press and hold the top button. When the Apple logo appears, release the button.
After the iPad successfully restarts, verify that the iPad is still charging. If charging, disconnect the Power Adapter cable from the iPad - and connect the cable directly to the Lightning port of the Camera Adapter. With the Power Adapter connected first to the Camera Adapter, you can now connect the Camera Adapter pigtail cable to the iPad.
If you have followed this procedure exactly as described, your Camera Adapter is hopefully recognised by the iPad. If not - proceed as follows…
Note that Lightning plugs can be connected in two orientations…
Disconnect the Camera Adapter pigtail from the iPad (the Camera Adapter still being connected to the Power Adapter) - and reconnect the Camera Adapter pigtail upside-down (reversing the Lightning plug). Does this resolve the problem? If the problem is resolved, the Camera Adapter plug is either dirty or faulty.
If necessary, repeat for the Power Adapter connection to the Camera Adapter. If this resolves the issue, then the USB cable that connects the Power Adapter to the Camera Adapter is likely to be the issue.
