USB Enumeration in OSX Fails #38

I observed issues with macOS (Sierra). For some reason the MAX3420 is only getting repeated requests to set the USB address. The requests will begin with some desired address value and slowly increment (requests come in every few seconds) until roughly 20 attempts were made. Eventually the host gives up and stops requesting the address be set. The OSX host never asks for the descriptor, so the device remains in this unusable state indefinitely.

Has enumeration been tested on OSX? I could not find anything definite through searches, nor anyone reporting this issue.
