Success!
In device manager I selected show hidden devices and found two instances of Bossa one was inactive the other active. I deleted both and reconnected and then when I selected the new com port I ran write and verify and all was well. It seemed that Windows held onto two com ports , one was hidden thus causing the problem. Something to bear in mind!
@zero-K My 0.5 gold plated chunky micro USB cable arrived this afternoon and solved the problem. If it's OK, I would like to suggest this solution, requirement, even be added to the Duet documentation. Also, @oliof USB3 or USB2 has nothing to do with the solution so please bear this in mind.
PROBLEM SOLVED.

@dc42 OK, good plan. I ordered a short (0.5M) USB cable with gold plated contacts. High transfer speed in spec... Hope it works, thanks for your kind help. I will post the results here.
@Phaedrux So, I suspected my Microsoft Windows 10 Dell laptop and removed all my personal files and rebuilt it. I installed driver files again from https://github.com/Duet3D/RepRapFirmware/blob/dev/Driver/WindowsDriverFiles.zip. I got the usual message after updating the USB driver with yellow triangle (right click, installed from the unzipped download (folder name WindowsDriverFiles) and it responded with "Unknown USB Device (Device Descriptor Request Failed). I have used the same USB cable that was working with YAT before I erased the DUet3 board. I use a powered USB hub. I see the little diag LED faintly lit, solid on, the bright red LED between USB socket and SD card and the green and red LEDs in the corner of the board on solid. Please can someone help?
@Phaedrux Yes, but I have also tried another cable (both worked before I erased the board) and I use a powered hub as well. I will try and find another PC... Thanks for your suggestions, I hope I haven't messed up the Board...

@Phaedrux Yes, I forgot about revealing hidden devices, I did that the Duet3 motion control electronics appeared in COM11 however it was not connected (greyed out). I am not sure what next step to take. At least the previous problem was solved but I am still unable to progress...
@droftarts Yes it is a 6HC, and I removed the erase jumper. I do not see a Bossa port...
I wish I never followed the advice of this Swedish guy on Youtube. I linked the erase pin on my Duet3 board and pressed the reset button (It was actually working via Yat etc before I did this). Now in device mananger I get yellow triangle in USB controllers, Unknown USB Device (Device descriptor failed). I downloaded the USB driver from https://github.com/Duet3D/RepRapFirmware/tree/dev/Driver but this did not help. I cannot do anything now. Please can anyone help?

@droftarts rebooted, same message from Bossa...
Could not connect to device on COM9
@meatfest still stuck. let me re-cap.
I have Duet3D board.
I am using Windows 10 (stopped using my Macbook Pro)
I have installed Bossa and Sam-Ba
I have updated the driver for USB and it shows Bossa Program Port (COM 9) in Device Manager.
With Sam-ba I get message:
Error h_handle returned zero
while executing
"TCL_Open $target(connection)" ....
With Bossa I get the message:
Could not connect to device on COM9
