STM32F4Discovery CDC HOST and Device

Question asked by fifre.pascal on Aug 2, 2013
Hi All,

I'm starting a developpement on STM32F4Discovery.
I want to use the two USB controler (HS and FS) in CDC Host and device to implement a serial to USB bridge.
OTG FS peripheral on device side to connect to PC
OTG HS peripheral on Host side to receive CDC USB dongles.
I have implement the OTG FS peripheral and it work fines with a PC on Windows XP.
I'have used the usbd_cdc_core.c and define USE_USB_OTG_FS.
Now I need to implement the host side. I have put a look at the DualCore code before.
Then I declared the USE_USB_OTG_HS and called the USBH_Init to initialize the Host side with USB_OTG_HS_CORE_ID.
Since I have been set the USE_USB_OTG_HS, the CDC on the device side won't receive any serial data on the usbd_cdc_DataOut.
The usbd_cdc_DataIn works fine.
I have seen in the usbd_cdc_core.c that it use the USE_USB_OTG_HS.
Does I make any change on this file?
Does anyone  have made any implementation like this ?

Best regards,
