UPDATE: I was able to control my custom HID device using IOHIDManager, but thank you for the help!

I started creating a simple driver using USBDriverKit and a demo app to test the system extension using OSSystemExtensionRequest.activationRequest(forExtensionWithIdentifier: , queue: ). The app has the .dext included and the system extension entitlement/capability. When I try to run it, I get: "extension failed category property check: extensions belonging to the com.apple.system_extension.driver_extension category require a later version of DriverKit to launch". Any ideas?
