Yes, the cookies are permanently set in the device's hardware. I
wouldn't suggest har-coding them though. Try using
IOHIDDeviceInterface122's copyMatchingElements instead of
IORegistryEntryCreateCFProperties. I think you'll find that it's more
efficient than trying to recurse through the properties tree yourself.

Here's some example code to illustrate its use:
