stm32c071kbt6 not detected as a USB device

[labubu]

以上就是我配置的所有内容。您能指出我的配置有任何问题吗？根据上述配置，我的设备现在在开机时无法在计算机的设备管理器中检测为 USB 设备。

Edit: That's all I have configured. Can you point out any issues with my configuration? With the above configuration, my device is now not detected as a USB device in the computer's device manager at boot time.

Hello @labubu ,

First, you should ensure the USB cable is functional and properly connected. Verify that the USB pins, jumpers on the STM32C0 board are correctly connected. 

Is the USB driver installed correctly?

Check also if the USB VBUS pin is properly powered.

Verify that the USB descriptors (device, configuration, and endpoint descriptors) are correctly configured.

If you can provide more details about the hardware schematics or USB pin connections for your STM32C0 board to further analysis the issue.
