STM32 USB

PSEBA.1 · ‎2025-02-27

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.

You're going to need to give more details of what, exactly, you tried - both hardware and software; Host & Device.

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.
