ESP32 Forum

Hi,

I will use the USB OTG interface of ESP32-S2-MINI-1-N4 module, but it does not have the USB ID pin.

• How can I use the ID property of the USB OTG standard?
• Is it suitable to connect the ID pin to the GPIO of the ESP32-S2-MINI-1 module?

Thanks in advance.

For what specifically do you need this? Do you want to use the OTG functionality, or simply act as a host or device? Asking as you don't need to connect anything to the ID pin unless you need true OTG.

I need the true OTG functionality.

Then you're probably going to run into more issues... we haven't properly finished the USB host driver yet, let alone thought about the OTG functionality, so you'd probably have to program that from scratch to get OTG stuff. Either that or wait until we get to it, at which point I assume there also will be proper documentation about things like the ID pin.
