STM32 USB

[PSEBA.1]

Hello,

 I can't get a USB connection with my stm32 cards, I tried several cards: Bluepill, Blackpill,
STM32F429ZI-DISCO, NUCLEO-F767ZI.

I still have the same problem "USN NOT RECOGNIZED",
do I need to install a driver ?

how can I solve the problem ?

Best regards.

Sébastien.
