STM32CubeMX USB Device generator bug

Today I played with CubeMX and USB CDC device and I found very silly bug in generated code.


I chose USB FS Device only mode and I used CDC class. Nothing else set. I did not enable VBUS.


Generated code enabled VBUS sensing but VBUS sense pin was not enabled.

I spent 2 hours to figure that out.


Please correct this mistake, disable VBUS sense by default or if you enable VBUS sense, then also initialize VBUS pin to sense voltage.


Have a nice day.
