Board: ESP32-S3-DevKitC-1-N16R8V (16 MB QD, 8MB PSRAM)
System: MacOS Ventura
PIO: PlatformIO Core, version 6.1.10b1
When building and uploading my project to the board with pio cli, the Writing phase progesses and stops at around 65-75%, with an error coming from pySerial:
A serial exception error occurred: Could not configure port: (6, 'Device not configured')
This process has worked and stopped working without notice.
I tested several USB/USB cables.
I tested other exact same boards in case of individual board failure
I rebooted to reinit the serial subsystem
I’m using the “left” UART port of the device.
Any advice could help a bit !

A serial exception error occurred: Could not configure port: (6, 'Device not configured')
Note: This error originates from pySerial. It is likely not a problem with esptool, but with the hardware connection or drivers.
