Prime - different hardware, Connectivity causes Prime HW verA Reset

[TomC]

Hello:

I've got two Primes which I'd just updated the OS today:

1. Software Version 2.1.14603 (2021 12 02)
Hardware Version A
CAS Version 1.5.0
Serial Number: 4CY34xxxxV
Operating System: V0.050.640

2. Software Version 2.1.14603 (2021 12 02)
Hardware Version D
CAS Version 1.5.0
Serial Number: 9CJ92xxxS9
Operating System: V2.060.650

I had purchase #1 long ago - probably shortly after the Prime Release.

I purchased #2 not too long ago (2018?).

#2 works just fine.

[Running Connectivity Kit on Win10, Connectivity Kit Build 2.1.14596 (2021 10 1).

#1 seems to work until...

I connect the connectivity kit. The connectivity starts up, connects to the Prime and shows its name in the window.
When I click on the calculator name in the window, the menu below appears for about a second, then the calculator power cycles.

Should I 'upgrade' this older hardware with a previous OS version?
[My apologies if this has been touched on before!]

Regards and Happy New Year,
TomC
