Hello, i have an issue with my board's vcp : stm32f407g-disc1 / MB997E

the st link port works perfectly , but the micro usb port ( vcp ) is not working , 
and yes i'm sure that it's a data cable not only charging, 
the interesting point is that before few months it was working on my laptop with the same cable, i can find two of them st-link vcp , and vcp , but now when i plug in the both cables , only i get st-link in the device manager,
i didn't make any update or removing drivers or that kind of stuff

here is what it's supposed to be in the device manager list :
