Can't get Driver properties using IORegistryEntryCreateCFProperties on iPadOS 16.1

Question

We are developing our Driver using DriverKit. In client App we successfully discover our driver but can't get IORegistry properties except IOClass. So in a client App we use following code to read properties:

    private func debugRegistry(device: io_object_t) {
        var dictionary: Unmanaged<CFMutableDictionary>?
        IORegistryEntryCreateCFProperties(device, &dictionary, kCFAllocatorDefault, .zero)
        if let dictionary = dictionary {
            let values = dictionary.takeUnretainedValue()
            print(values)
        }
    }

Output is:

{
    IOClass = IOUserService;
}

We tested same code on macOS and output contains about 20+ properties. It looks like IOKi doesn't allow to read other properties except IOClass.

Environment:

• Xcode - Version 14.1 beta 2 (14B5024i).
• iPadOS - iOS 16.1 (20B5050f)
