I am trying to make USB FS driver detection by host PC.

I made some changes to the driver as per the youtube link:

 

12. STM32F4 Discovery Tutorial : USB CDC Virtual Com Port - YouTube 

 

The application is sending "Hello World" string every second to the Serial port.

 

The problem is I am not able to detect the USB driver on the host Windows 7 PC.

I installed STM32 Virtual com port driver (my device is stm32f411rct6).

It is showing "Unknown device" or "USB device not recognized" 

When I see the properties of the device, it says "Code 43".

 

Please update me about this.

 

Thanks,
