This happened with iOS 10.1 and presently I am using iOS 11.2 and still getting intermittent annoying warning messages saying that the Smart Keyboard was an unsupported device:
“Accessory Not Supported.This accessory is not supported by this device. Ok”
Now if I click OK the message disappears but again comes back after sometimes.
The workarounds are disconnecting the keyboard and check for any debris interfering magnetic connectors with the device. Cleaning of magnetic connectors has been suggested.
Apple has come out with the following resolution:
If your iPad Pro doesn’t detect your Smart Keyboard or you see an “Accessory not supported” alert on your iPad Pro, make sure there’s no debris or plastic covering on the Smart Connector pins on the keyboard or the Smart Connector on the iPad Pro. Also, try these steps:
- Make sure that your iPad Pro and Smart Keyboard are in the Type position.
- Remove the Smart Keyboard from your iPad Pro.
- Restart your iPad Pro.
- Reconnect the Smart Keyboard.
But it is absolutely useless. Cleaning the magnetic connectors and following the above steps are of no use. Not helpful at all.
I am looking for a real fix.
