Thanks for taking the time to explain!

So your original comment / request was regarding USB specifically then?

I ask because I'd have guessed (possibly incorrectly!) that implement HID via GATT (BLE) you'd be able to support anything the BLE hardware revision could implement?

Perhaps the disconnect for me is that it's unclear when there is some special hardware that exists within the ESP32 itself (I think I2C, I2S, etc would be examples of this) vs something you are just implementing by manipulating the IO pins. Perhaps HID is one of those things?

The BLE and USB peripherals are separate, so limitations in USB HID do not carry over to BLE HID.
