USB enumeration failed !

Question asked by ln.thierry on Dec 14, 2015
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 ?????
