iOS upgrade breaks card reading
After upgrade to iOS 16.5 camera connection kit/card reader no longer boots cards that used to read just fine. Says not enough power…
Question marked as
Presumably you are using an Apple USB3 Camara Adapter with your iPad - and to this is connected a card reader via USB. As you may be aware, many USB peripherals require more more power than the iPad’s Lightning port can supply - and for this reason you must also connect your iPad’s Power Adapter to the Lightning power connector of the Camera Adapter.
Subsequent to the iOS/iPadOS 16.5 update, there is an issue with charging the iPad from USB Type-A Power Adapters, via the USB3 Camera Adapter - regardless of the Power Adapter’s power output.
The current workaround is to use an Apple USB-C Power Adapter with a USB-C to Lightning charging cable.
