Usb init failed

[gwilherm]

Hello,

I am trying to use the mini USB Host shield with an ESP32 as in your schematics but I only get "Usb init failed!" error (I tried with 3 different devices).
Am I doing something wrong ? Is there a way to know if the shield works?

I also tried the USBH_MIDI_dump example and same result.

Additional question: what is the purpose of the resistor on RESET pin?
