STM32F4 DISCOVERY + STM32CUBEMX + USB-OTG-FS as master + Mass storage role does'nt work

Question asked by Mikael.Elharrar on Jun 10, 2014
Hi guys,
I'm working on ST32F4 DISCOVERY board.
I generated a STM32cube project with freeRTOS + FatFS + USB-OTG-FS as Master and it doesnt work.
USB LED (vbus) is not light and the USB key doesnt receive any voltage.
Someone knows if there is a bug in this configuration ?
My board is OK, because I downloaded the example with firmware upgrade from USB key and it is working ....
Here attached my .ioc project.
