Use OTG Guru to get a list of the USB devices connected to the OTG port.
For each device, the app will display:
- VID, PID
The app will list all the available interfaces.
For each interface, the app will list all the available endpoints and their details.
I hope that you will find the OTG Guru useful if you are developing USB devices or drivers.
