Have these two products:

      https://www.dfrobot.com/product-2595.html

I have installed the usb drivers:

   CP210x_Universal_Windows_Driver

   CH341SER

I have changed the usb cable.

I have connected a regulated 12V supply to the terminal block.

When the ESP32 is connected to the terminal block, the USB port does not work for serial connections.  I cannot use a serial monitor when on the terminal block for debugging.
