Hi,

\STM32Cube_FW_F3_V1.4.0\Middlewares\ST\STM32_USB_Device_Library\Core\Src\usbd_core.c (version V2.4.1)

The last update with ''Prepare endpoint for premature end of transfer'' modification doesn't work.

I had to remove these lines to have a correct USB enumation.

        USBD_LL_PrepareReceive (pdev,

                                0,

                                NULL,

                                0);

Is it normal ?????
