If I power it through the USB cable, everything works fine, but if I power it through the 5V pin, with a 5V supply, the behavior of the controller is not normal. Someone suggested me (and what I see around the web) to update the ST Link firmware, so I did, and still the same. Have anyone had this kind of issue?

I'm not using Mbed. I'm using CubeMx (HAL Library) and SW4STM32. My ST Link version is the 4.2.0.
