If the connection is correct but the list is empty after clicking install, please check
1.Does your computer have the CP2102/CH340 driver installed? (A download link will pop up after clicking the cancel button on the installation page)
2.Is the USB cable a 4-core data cable capable of transmitting data, rather than a 2-core cable used only for power supply? (When connecting the ESP32 chip to the computer using a USB cable capable of transmitting data, there will be a sound indicating that a USB device has been inserted)
If prompted 'Try resetting your device or holding the BOOT button while clicking INSTALL', please hold down the boot button throughout the entire process from selecting the device until the installation percentage appears (there are two buttons on the left and right sides of the ESP32 USB port; you can try them separately).
