> Joseph Moschini: > I was wondering if this issue was ever solved ?, I am having the same problem on STM32F407.
Refer to the recent ST USB library,
STM32F105/7, STM32F2 and STM32F4 USB on-the-go Host and device library v2.1.0 www.st.com/.../stm32_f105-07_f2_f4_usb-host-device_lib.zip
ST USB stack supports all device engines, FS, FS on OTG_HS, ULPI on OTG_HS.
You'll find port pin setups in usb_bsp.c of each device project, for example, STM32_USB-Host-Device_Lib_V2.1.0\Project\USB_Device_Examples\AUDIO\src\usb_bsp.c Find USE_USB_OTG_HS and ! USE_ULPI_PHY macros.

I pasted the USBD_Init, that was the main change. If you want I can send files if needed.

Ouch! I need the driver for USB Host... I modified GPIO, RCC, IRQ as you done for USB device but it doesn't work. http://www.keil.com/forum/21431/
Anyway, thanks a lot!
