Important Notice

To ensure successful STM32 programming, please pay attention to the following:

• Some computer USB ports may experience unstable programming due to driver or signal compatibility issues. It is recommended to try connecting to a different USB port.
• If changing ports does not help, an effective solution is to connect via an external USB hub, which often improves compatibility.
• When the programming software reports the error message shown below, also try using a hub first. If the issue persists, please check or use the host computer for programming.
