I am not able to use my lightning camera adapter with my iPad 6th gen running 17.6.1

I too have a Lightning to USB3 Camera Adapter (Model Number A1619) - and it functions perfectly with iOS/iPadOS 17.6.1. The Adapter itself has firmware version 1.0.5:

Settings > General > About > Apple USB Camera Adapter > Firmware Version

If you are experiencing difficulties post-update to iPadOS 17.6.1, either the Adapter itself has not automatically updated to its most recent firmware, the Adapter has a fault, or you have some other issue.

Remember, the Adapter must be connected to external power, via its own Lightning pass-through power connection, for the majority of connected USB devices.

As you are using a third-party USB Adapter, I can't offer additional comment - other than to suggest that you try using the Apple Lightning to USB 3 Camera Adapter:

I have just noticed the same issue with my iPad pro after the iPadOS 17.6.1 update.

My midi controller is not connecting to my IPad piano app or garage band.

so is it the camera adapter that has been disabled?

Apple, why do you do this to your customers

You are very welcome.
