我正在使用 adafruit STM32F405 羽毛，并在 stm32cubeide 中为它编写了一个程序。我USB_OTG_FS在中间件下的 USB_DEVICE 下启用并选择了 VCP。CDC_Transmit_FS()我在我的main.c文件中使用发送了一条简单的消息。然后我想使用 minicom 显示消息，但是当我插入 stm32f405 时，它没有被识别为虚拟 com 端口。请有人帮忙解决这个问题吗？

这是我从中得到的dmesg

读取 USB 设备描述符时似乎出现错误，有什么想法可以解决这个问题吗？

MX_USB_DEVICE_Init 末尾的 HAL_PWREx_EnableUSBVoltageDetector() 用于显示较旧的固件。

我从 1 月到 7 月更新了 IDE、MX 和 STM32CubeF4 版本，我的 USB_OTG_FS 开始工作（上面的调用在最新版本中不存在）。
