STM32F407VET6 Development Board gives a "Unknown USB device(descriptor failed)" error


The board is newly purchased from ROBOKITS INDIA, and i received it about 4 days back, now when im connecting it to my laptop, it gives an error saying device descriptor failed, now i tried to do the other solutions like uninstalling the driver, restarting laptop and also disabling the fast startup, still no luck.

Do i need to configure the USB_OTG as dual device type and then Flash it to make it work or the hardware is just defective?
