ESP32+CAM Driver Connection Issue

Projects General Guidance
1

Hello there. I have been trying for over a week to connect my esp32+cam dev board to my computer so I can start my project but I have been stuck. I got it to work once and then never again. I have a shield to program it: ESP32-CAM-MB. I believe I have the right driver installed on my computer: CH340 but it doesn't connect still.

Any help would be VERY much appreciated!

Here's the error I get:

Arduino: 1.8.19 (Windows 10), Board: "AI Thinker ESP32-CAM, 240MHz (WiFi/BT), QIO, Huge APP (3MB No OTA/1MB SPIFFS), 80MHz, None, Disabled"
esptool.py v4.5.1
Serial port COM4
A serial exception error occurred: Cannot configure port, something went wrong. Original message: PermissionError(13, 'A device attached to the system is not functioning.', None, 31)
Note: This error originates from pySerial. It is likely not a problem with esptool, but with the hardware connection or drivers.

listen
we also had the same error ( group ).
we went to a setting in the esp 32 cam board selection or somewhere, i dont know what it is or where it is but when we enabled it and went to debug, it said that it is not connecting to home wifi and it only connected to hotspot.

also

Note: This error originates from pySerial. It is likely not a problem with esptool, but with the hardware connection or drivers.

this means that dont use pyserial and use esptool. we found the problem using esptool.

Not entirely sure what you enabled and if that helped or not. I did however find this thread (linked below) where someone had a similar issue and essentially solved it by replacing the esp32-cam-mb with the standard USB programming adaptor. I will assume this will solve my problem too and get one so I can test it.
