I'm implementing a product based on an i.MX6ull SOM. On our board we will use a USB device operating on 3.3V. However, it seems like the USB bus does't work in host mode without 5V attached to the VBUS pin(s).
I would like to avoid implementing a 5V supply just to get USB working. So my question is, is there anyway to make the USB bus(es) work without it?
