Hi, and thanks for the quick response.
I tried the roll back but found that the Lolin S2 Mini was not an option in that version. I tried the Wemos D1 ESP32 and it would compile but the upload failed "Chip is unknown ESP32".
I am going to try and use an external FTDI to avoid issues with USBCDC. If that does not work I will just use the D32 module.
Thanks for the great body of work and support. I cannot even imagine how much work it must be to try and cover all the different chips and modules.
The integration with Home Assistant makes this a breeze!

Cannot compile on Lolin S2 Mini with USBCDC
I am trying to build a button sensor on a Lolin S2 mini board. I am using the Binary Switch Sleep Sensor example code from the MySensors library.
When I attempt to compile the code I get an error message:In file included from c:\Users\Rick\Documents\Arduino\libraries\MySensors/MySensors.h:61,

If I disable "USB CDC On Boot" under Tools, the code will compile and upload but then I am unable to use serial monitor to debug as there is no port to connect to.
The exact same code compiles and runs just fine on a Lolin D32.
I am using Arduino IDE 2.0.2 running on Windows 10. Board library is esp32 2.0.5. The radio is an RFM69CW.
I found a reference that suggested adding a Serial.begin() statement to the setup to initiate a serial port after the restart but this did not work.
I also found it odd that I could compile and run a simple program that reported the SPI pin assignments via serial monitor and it worked fine!
Any suggestions appreciated.
