Hello, I'm trying to use the usb peripheral embedded in stm32f407vgt6 as device. I connected D+(from host) to D+(of my MC) through 22Ohm resistor and D-(from host) to D-(of my MC) through 22Ohm resistor also Vbus(from host) to Vbus(of my MC) without resistor and left ID pin(of my MC) floating. I read that I should connect Vbus to D+ through 1.5KOhm resistor in order for the host to recognize when device is connected, is that correct? and is my circuit correct?
