Conflict with USB

[RobinMosedale]

USB becomes unavailable: Executing task: C:\Users\robin.platformio\penv\Scripts\platformio.exe device monitor --environment esp32s3 --port COM19

UserSideException: could not open port 'COM19': FileNotFoundError(2, 'The system cannot find the file specified.', None, 2)

• The terminal process "C:\Users\robin.platformio\penv\Scripts\platformio.exe 'device', 'monitor', '--environment', 'esp32s3', '--port', 'COM19'" terminated with exit code: 1.
• Terminal will be reused by tasks, press any key to close it

This is a bare esp32N16r8, no peripheral wired

ILI98341/PCM5102/esp32n16r8 standard configuration for build as below

USB becomes inoperable as soon as image is loaded. Windows declares an unknown device on the USB No serial terminal output can be obtained. Probably a pin conflict with the standard Devkit esp32n16r8

I had a similar issue the other usb port worked for me

[RobinMosedale]

Thank you. That worked. Something must be clashing with the USB ports
