I have a blackpill board with STM32F411 48 pins IC and CubeMX/CubeIDE at lastest versions. The USB is configured as device CDC, no Vbus.When I flash the board with generated code and plug USB in Windows 10 I get an error "invalid device descriptor"...

I found the solution, I have to increase the heap (0x1000), but this isn't enough to solve. I need to change the automatic clock configs of CubeMX that use internal 16MHz clock as source to core.The image bellow show the way that works.

But the automatic code generated by CubeMX isn't reliable?
