I spent a few hours trying to upload the example code to the board I received today. The Arduino IDE detected a serial device, but every time I attempted to upload, it returned the error "Failed to connect." Later, I realized that the serial port detected by the IDE wasn't the ESP32 but rather another device on my laptop.

After hours of research, I found this issue mentioning that a pre-installed software, brltty, was silently blocking the CH340 USB driver. The workaround (for now) is to uninstall brltty: sudo apt-get remove brltty
