With a good cable and the right driver installed, your PC shoud present a COM port even if you would completely remove the ESP32 module from the board, because the USB communication is not handled by the ESP32.

You might just need to install a driver for the USB to serial chip on your dev board. So if one dev board works and another one doesn't, that does not necessarily mean the board is defective. Although the ESP32 module may be the same, you might have a dev board with a different USB to serial converter than other devices you might have tested on your computer. Without a driver the chip probably turns up as unsupported or unrecognised device in your hardware list. If you have a driver for that chip instaled, otherwise it won't work. This chip communicates with your computer, resulting in the creation of a virtual COM port. A dev board typically includes some sort of USB to serial converter chip (sometimes refered to as FTDI).

Don't just check if it charges your phone, but check if you are actually able to transfer data.Дў) The USB connection is not handled by the ESP32, as an ESP32 only has serial lines (rx and tx), no USB.

So make sure you have a 'real' USB cable by testing it on another device. This is different than the Uno, which has a dedicated USB-to-serial chip on the board, but can only operate as a USB serial device. If you would use a cable like that, the result would be what you described. That means it can operate as a few different USB devices: asynchronous serial, keyboard or mouse (also known as Human Interface Device, or HID), and USB MIDI. IвЂ™ve seen reference to some add-on boards needing the ACM driver instead (which can be built as a module and copied ot the Jetson). The serial FTDI device driver is installed by default.

However, realize that USB serial devices need a driver for whichever chipset is used.

If you do not see an available serial port in the Arduino IDE after plugging in your board and waiting a moment, then you may need to install the drivers by hand. Not enough is known about your case to answer. The Arduino Uno will appear as a ttyACMXX device. The SparkFun RedBoard will appear a ttyUSBXX device. I assume these have only 2 out of 4 wires: ground and +5V, but no data lines. Please choose the relevant version according to your computers operating system and click the download button. In the Arduino IDE, click Tool -> Ports to ensure the device has been recognized. Apart from what kolban said, I would like to add two comments:ДЎ) Nowadays there are a lot of cheap (Chinese) USB cables that can only be used for charging or powering devices.
