Description

Enabling both USB MSC and CDC causes unstable connections in the CDC. The CDC after some times fails and the only way to recover it is to reboot the ESP.
When MSC is not enabled the CDC is super stable.

Maybe a larger stacksize of TinyUSB might help. (default is 4096)

Sketch

#if !ARDUINO_USB_MSC_ON_BOOT
FirmwareMSC MSC_Update;
#endif

void setup()
{
  Serial.begin(115200);
  //no need to begin MSC_Update. The CDC will become unstable after a while even without exposing the flash drive to OS.
}
