ESP32-S3-WROOM-1: Error 43 A request for the USB device descriptor failed

[jwalkerbg]

Hello,

I have devboard with ESP32-S3-WROOM-1. My problem is that one of two USB ports began to be not recognized by Windows. Windows stops it with "Error 43 A request for the USB device descriptor failed.". Before this to happen I was able to use this port.

I thought that it is hardware problem, however it seems it is not hardware problem.

After I press and hold pressed BOOT button and then RST button, then Windows sees this port. Even, I am able to program the device with with flash_download_tool_3.9.5.exe. However, after programming, when I press RST button again, Windows begins complaining with the same "Error 43 A request for the USB device descriptor failed.".

The devboard has second USB port, and I am capable to program the device via this port, But I am not knowing how to "unlock" the first USB-COM port...

Any thoughts and suggestions would be welcome.

Could be as simple as software initializing GPIO19/20 to GPIOs. These are the USB pins on the S3, initializing them to another function disables USB.

... and it was really that simple: GPIO19 was selected as SDA of I2C. Moved SDA to another pin and the port began to work again.

Thank you for the suggestion.
