The documentation mentions that the current version of ESP-IDF supports only single device connected to the ESP32 host: https://docs.espressif.com/projects/esp ... imitations
Does a USB hub counts as a device? Will a single device thought a usb hub work?
ESP32 -> usb HUB -> HID device
Given that one day multiple devices will be supported I want to future-proof my hardware and put a usb hub on-board.

Re: ESP32-S2 USB OTG - USB Hub support?
No. If you connect a hub to the S2 OTG port, the hub is the only thing that the S2 can talk to, not to any devices behind it.
