I am not able to connect the DDRC-88A after performing the Main I/O board and MCU firmware upgrade successfully after following the tips in this forum.

I followed the instructions on pg 79 of the DDRC-88A manual.
I reboot the WIn10 laptop. Connect the USB cable to DDRC-88A. ( there is no Win10 chime sound )
Power on the DDRC-88A. ( i removed the top cover. I can see the Blue LED light on the main board blinking)
Launch DDRC-88BM login and click Connect Button. I can see a few (3??) small windows opening and closing rapidly. Too rapid for me to read what are the message in these small windows
I see the <Retry connection 1, 2, final time) message and finally get a <Cannot connect to DSP. Please plug in the board> message.

I have retry the DDRC-88BM connection steps severals time on 2 different laptops.
In all cases, I am not able to establish a connection to DDRC-88A from DDRC-88BM plugin.

I would like to request advices whether I missed any steps or how to troubleshoot the connection failure issue.

Thanks for all the help in advance.
