@DTS Engineer Hi Kevin, Thank you for your advice on this thread. Despite the great tips you've shared in this thread, we are still a little stuck and were wondering if you could help us : we initially submitted a DriverKit PCI entitlement request, but Apple Developer Relations replied that com.apple.developer.usb.host-controller-interface is not a DriverKit entitlement and should instead be requested through Feedback Assistant, using the macOS / USB / Other Bug flow. Following that guidance, we submitted a Feedback Assistant report on May 12. The report includes all requested information (Team ID, Bundle ID, overview etc) The option "Other Bug" was not available so we selected "Incorrect/Unexpected Behavior" instead. Available options were (and still are) “Incorrect/Unexpected Behavior”, “Application Crash”, “Application Slow/Unresponsive”, and “Suggestion”. Our Feedback ID is: FB22759805. The request is still open, and we would be very grateful if you could help confirm it has been routed to the correct component/team for review. Thank you very much for your help.
