Hi Steve, It’s good that the COM port is created and shows up cleanly in Device Manager. The board has the CH340 chip (usb-serial interface). A feature (?) of this chip and driver is that the COM port number is differen depending on which usb socket you connect to. The serial properties of the port don’t matter, the sketch will set what it wants.
The Oscilloscope sketch seems to be trying each port, looking for something, not finding what it wants. Have you loaded the Arduino with whatever software does the scope’s data gathering? If you have why is it not working? Hmm… Suggest you examine the sketch where it looks and rejects. You are using an ESP32? Is that the only Ard/ESP you have? We may need another channel to see what’s going on e.g. LCD screen, software serial, WEB? (slow to put together but I have used it).
