Hi all,
I'm a complete beginner when it comes to ESPHome, but I hope you can help me!
I use the ESP32-S2-DevKitC-1 device and in general everything works fine.
But when want to set up the component USB Host UART Interface for this device I get the following error message No matter what I enter in the ID field as you can see in the screenshot.
Do you know which number or text I need to enter in this field for my device?
Thank you very much and kind regards
Thomas
Here is the Validate output, but I do not know if this helps...
