USB Device Library support for STM32F429 Disco

The base address for the USB_FS peripheral seems to be wrong. Check USBRegs_STM32.h and replace the #define OTG_FS_BASE (AHB2PERIPH_BASE + 0x0000) with something like #define OTG_FS_BASE ((uint32_t )0x50000000U) or #define OTG_HS_BASE ((uint32_t )0x40040000U). I haven't tested this yet, make this change and try again. Or you may use the USB-VCP in the debugger. Simply use USART2.
