Michael Armani, aka Marmani on the Discord channels responded to the conversation with a point that I did not know, and is not mentioned on the Troubleshooting guide.

If using the Duet instructions for SAM-BA.
(https://duet3d.dozuki.com/Wiki/Installing_and_Updating_Firmware#Section_Fallback_procedure_Num_3)
Please DO NOT select at91sam4e8.
-That describes the Duet Wifi, not the Maestro.
Instead choose ATSAM4s8.

However, we do not use this tool and strongly recommend using Bossa instead. Please see our repair instructions https://coda.io/d/M3D-Public_dzE73kMbIAL/Duet-Maestro_sui8n#Cards_tubJG/r1, I would say at least 50% of the time we recover a board with funky behavior (No usb response, SD card reading, even sometimes a stuck pin). Updating the firmware helps with these, and sometimes the board just needs a refresh.

@bot you are absolutely right, thats not a bug, it's a feature! I was doing it wrong, everything works perfect, it's all perfect.

Been working with a few and it seems that they are unable to get a response when the Erase pin was used. One did get a partial response but once the pin was cleared and the board reset it never came back and even though all seemed normal, it never presented to windows.

I cannot validate this further as no one has sent their cards to me for help.
-Though to be fair this is not a service I am offering, yet. I also have no contract with M3D or Duet to offer services so if I find a card really is dead, I have no idea where to go from there in terms of a proper hand off for warranty if any at all.

I think if I or we can Identify the reason why some ERASE pin cards, will not present at all. Then more can be helped to recover from these kinds of mistakes. -For now I have been trying to warn other users to NOT use the ERASE pin unless told to by support staff.
