Can anyone check the below schematics of ESP32-S3-WROOM-1-N16R8, I am using windows 11 and unable to detect the usb com port to program the controller. I tried to follow the schematic of a board of ESP32S3R8N8.
Attached is my schematics. I used CH334F and CH340K. Drivers are installed as well.

Where is the boot button? A lot of times the IO 0 is used to but the ESP32-S3 into boot mode then Windows will recognize the USB port as a COM port. Here can find an example:

Thank you for the reply.
GPI0 is connected with GND via push button. I highlighted it with red in the schematics. I tested the board on multiple PCs, multiple wire, still getting unknown USB driver.
Anyone please help.

Also note that the programming is done via a serial-to-USB converter chip: you should be able to find that regardless of the ESP32 state.
In general, I'd try to figure out which chips *are* detected: you should see both the USB hub chip as well as the USB-serial converter. I have no idea how to check for those under Windows, but the system log under Linux (dmesg) may give you more info when you plug the board in.
