Hi all, Does anybody has any idea what is "The parameter is incorrect" error. I am using nucleo f429zi board. the problem occurs when i am using ethernet with the USB. The PC can detect the virtual com port but gives error when you try to connect to it.

If i disable the ethernet (comment the MX_LWIP_INIT function) the USB works fine. I am only using the cube MX generated code no fancy thing at all. The next thing I tried to do was to do the same thing on STM3249zi eval board but I was surprised to see that USB was working fine with the ethernet, no errors at all.

The question is that is it something to do with the hardware?
