STM32F4Disco + VCP + Windows10 issue: error code 10

[mmed]

Hi all,

I want to handle STM32F407 Disco via VCP. In the first case, i tried to configure UART but when i connect my USB TTL converter to my PC: it informs me that VCP error ''This device cannot start(code 10)''.

I thought that the probem is related to my USB converter

Then i tried to configure CDC USB:

USB_OTG_FS on mode Device only

activate USB_Device middelware in CDC mode

check the CubeMX file attached for more details

but the problem still exist!===> VCP error ''This device cannot start(code 10)''.

and here is the define in "usbd_desc.c" file

#define USBD_VID   1155

#define USBD_LANGID_STRING   1033

#define USBD_MANUFACTURER_STRING   "STMicroelectronics"

#define USBD_PID_FS   22336

#define USBD_PRODUCT_STRING_FS   "STM32 Virtual ComPort"

#define USBD_SERIALNUMBER_STRING_FS   "00000000001A"

#define USBD_CONFIGURATION_STRING_FS   "CDC Config"

#define USBD_INTERFACE_STRING_FS   "CDC Interface"

=====> Please how can i handle to fix this issue! if there is a wrong value generated by CubeMX! or a change that should i do in my environement (PID, VID....)

this is a real problem for me that block my project0

Please any solution or workaround for this

many thanks
