No device detected - Electronics Explorer

[philipg]

The Electronics Explorer board isn't being recognized by Waveforms. I've been using it successfully for many months. But it started failing yesterday, after experimenting with the Digital inputs and a Arduino Nano. 

Launching Waveforms reports the following errors:

1) On every launch: "No Device Detected"

2) Rarely:     JtscProgramDvc failed SERC: 1004 
                     FPGA programming failed.

I've gone thru all of the suggested troubleshooting steps for the Electronics Explorer (several times) with no luck. 

Listing the Macbook Pro's connected USB devices from the command line yields the 2 identical error messages shown below.
Also, the list of USB devices does NOT included the Electronics Explorer.

The Macbook Pro is running Montery 12.6
Waveforms is running 3.18.1 64 bit Qt5.12.9

Any suggestions would be appreciated. Thank you.

FYI. This problem has been resolved. I recently started using a third party power adapter for the Macbook Pro. It appears to have interfered with usb connectivity. Running the Macbook on its battery or using Apple's power adapter resolved the problem.
