Hey Guys,

After I programed vcp for STM32F427 Eval board by following the example of STM32F429Discover board, but when I plug it into the PC, The PC can find it but always get a warning marker on the Device manager as shown below. Anyone have the idea on this problem?

That's actually a dumping ground for all the above mention interrupts, with weak linkage. Determine which interrupts you are enabling, and for which you have created handlers.

Most likely one related to the USART you are using, or the code expects you to be using, or may be a TIM2 or SysTick?
