Switched my STM32F4 discovery and now Virtual Com port is not working

Hi,

 

i swapped my first STM32F407G-DISC1 discovery board for a new one and now the ST-Link onboard doesnt show up as a virtual com port in Windows 10 anymore. 

 

I flashed the St-Link with the new firmware, it runs V2.J30.S0 STM32 Debugger now.

 

I also installed the current Windows driver from here.

 

Now i read the DISCOVERY boards dont all have the virtual com, but in this site it says that my order code should have it (on my PCB is a silk print next to the USB connector that says "STM32F407G-DISC1).

 

Can it be that the silkscreen board code doesnt correspond to the "order code" which is mentioned on the above website?

 

Please help since i really need the virtual COM port.

 

Patrick
