STM32CubeMX & STM32F4 Discovery and a Simple HID USB issue

I have build and tested the STM32cube Demonstration project using MDK-ARM for the STM32F4 Discovery and it worked fine.

So I tried my own very simple project using STM32Cube interface to create the source for a USB HID device. but when I plug the USB cable in I just get ''Unknown USB Device (invalid Device Descriptor) '' in windows device manage

Can anyone help - It must be a simple issue but I have spent all day looking and can not resolve it.

Hi owen.j,

Verify that you entered the PID and VID in the code.
