Problem solved!

You need to use micro-usb port instead of the mini-usb port to flash the
micro-controller chip STM32F407VG on the STM32F4DISCOVERY board.

The mini-usb port is connected to the STLINK chip STM32F103C8T6 on

I wanted to flash the STM32F407VG chip on STM32F4DISCOVERY board.

If I am wrongs or could it be flashed using mini-usb port please share it
with me for my knowledge.

I am using this link for assistance:
