ARDUINO USB CH340 USB NOT FOUND INSTALL
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. For obvious reasons, chips in the CH340 series used for USB to. This cable works properly as a usb to full modem rs232 port converter.

ARDUINO USB CH340 USB NOT FOUND DRIVERS
Usb serial ch340 chip, usb drivers dont know it. If you have a driver for that chip instaled, otherwise it won't work. ESP32 boards are not natively supported by Arduino IDE, so you need to add them manually. Not knowing much about serial communications im assuming that. 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.Ģ) 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. If you would use a cable like that, the result would be what you described. I tried downloading the CH340 driver, but it did nothing :( It has always worked before, but it suddenly won't work all of the sudden. When I plug my USB cable into the USB port, the COM port doesn't show up under the Tools > Port shortcut, making me unable to upload my code. I assume these have only 2 out of 4 wires: ground and +5V, but no data lines. I use Arduino IDE and the Arduino UNO X board. Apart from what kolban said, I would like to add two comments:ġ) Nowadays there are a lot of cheap (Chinese) USB cables that can only be used for charging or powering devices.
