Solution
If the iOS device is not Supervised, the user must disable 'USB Accessories' on their iOS device. If the iOS device is Supervised, check (enable) 'Allow USB Accessories while device is locked' on the Apple iOS management tool. Note: The label for this configuration setting varies between MDM products. Ensure the setting is configured to disable USB accessory connection unless the device passcode is entered.
