How to Get Mouse and Keyboard with USB working on Retroarch

I Tried Lighting to USB 3 Camera Adapter.

It works with my Backbone Controller but when I plug in with Keyboard and Mouse nothing Happens. Did both 1 at a Time and the a Adapter that has 4 USB Connections

Why is that and can it be Fixed?

Got New Update but Keyboard/Mouse does not work on RA

Can use Keyboard for other Apps but not RA
