It seems that Setup Manager somehow does not get notifications from Windows telling about connected/disconnected USB devices. That will cause the behaviour you see. The firewall has nothing to do with that, neither do you need rules in it, nor is there any service which has something with that to do (unless other USB devices work ok).
I assume you have tried starting the Setup Manager with and without the RRC connected? I also assume that you do not have more than one RRC/WS connected to the PC at the same time?
