Description
开发环境
- 野火骄阳 STM32F407
- 使用Rt-thread Studio 创建STM32F407 工程, 使用
4.0.24.0.34.1.03.15 lts - 使用STM32CubeMx 创建项目 配置USB RCC
- RT-thread Setting 设置
以上步骤都相同的时候，使用rt-thread lastest 就可以正常枚举USB，有熟悉的人知道 具体是那些地方发生一改变么？
已经尝试的步骤
- 拷贝 lastest 中的 STM32 LIB
- 更换 rt-thread/components/drivers/usb 中的 USB core lib
- 更换 driver 中的
drv_usbd.c
到 4.0.2版本中都无法正常枚举？
现在非常疑惑，最新发布的4.1.0 也无法正常枚举
我已经把自己的代码移植到 lastest上了。USB可以正常枚举，所以应该不是我自己的代码引起USB出现无法枚举的问题。

Research direction
Compare the working latest version with RT-Thread 4.0.2, 4.0.3, 4.1.0, and 3.15 for the STM32F407 USB path. Start with components/drivers/usb and driver/drv_usbd.c, including the STM32 library changes already mentioned, then identify the version difference that prevents USB enumeration and verify it on the stated STM32F407 setup.
