Hi @rogerli
Thanks for the pic. OK good. That is all normal, and your MCBL-00001-1 is from newer stock that is much more reliable than older MCBL-00001's a few years ago.
Now, regarding the specific plug-in board with Microhard, I wonder if you had an issue we are aware of as reported from previous forum users and we capture that here:

So, when you install the Microhard, be sure the bottom of the MH board is not touching J5. If it does, that can make the system and then LEDs go wonky from shorting out stuff and prevent you from seeing the devices with lsusb.
If you can get past all of that then someone from SW will have to chime in to help you further.
I just jump in when I see potential HW related topics 🙂
