I see in the release notes for DA 11.1 which came out December 2019, on the issues list there is STILL after many years later,this issue of the of the following popup still occurs:
USB/Port Security Alert, The operation you are attempting on the device \Device\Hardisk0\DR0: was denied because of restrictions in effect on this computer (embargoevents.exe).
How many YEARS is it going to take developers to FIX this issue? It doesn't matter how benign it is quite frankly, but when you have users questioning it, telling them to ignore it isn't the most professional response.
