minimum circuit to have STM32F407VGT6 with USB working properly as a USB host

[MAlek]

Hi guys,

does anyone draw a circuit to get the stm32F4 MCU with USB connector working properly .

Thanks

Inside reference manual there is a minimum "schematic" for OTG USB FS in Host mode.

F4 series has an internal FS PHY.

I tried it and it works properly.

Although EMI filters and ESD protection, both are recommended.

Most cheap Chinese F407VG boards use this minimal configuration.

Hi Vangelis,

thank you !

But, i am not understanding why my code is not working ...

I am using this board :

its schematics:

I am beeing able to flash the code using stlink and usb (dfu), but when i connect the board to the pc it does not show the HID device.

What could be causing the problem ?
