Hello Everybody,

I am trying to get the USB CDC device only with VBUS sensing to work. Sadly I get allways the device descriptor request error (Error 43) nd the device won't enumerate with my PC host.

Most possible solutions or discussion about this problem are more than one year old and do not utelize the new STMCubeIDE which inherits STMCube isnide the IDE and did also modify the USB driver lib.

Pleae find below images of my initialization settings:

It is the first time that I work with USB together with a STM32 MCU.

I would be glad if somebody can help me with this problem.

Benjamin
