@Rbb666 这个PR还能过吗？ |

CI问题处理一下，应该是这个PR引入的 |

这个PR只修改了/bsp/nxp/imx/imxrt/libraries里面的一个文件，只有三行变化，请在files changed列表中查看，而出问题的BSP是/bsp/nxp/imx/imx6ull-smart，可以肯定与这个PR没有关系。用仓库中最新的版本测试imx6ull-smart，也存在编译通过不过的情况。 |

感觉是ci的工具链设置的不对

我clone到我本地的仓库中这个BSP也是编不过的，所以我很好奇，我后面那个PR（10361）他是怎么编过的？ |

看了下是这个PR引入的6ull的编译：#10273 |

我知道了，qemu已经把toolchain改过了，所以其他ci能过 |

这个直接合吧。ci问题后面再修复一下。 |

拉取/合并请求描述：(PR description)
[
在imxrt的BSP/libraries中，USB的驱动存临界资源未保护的问题，通信过程中有一定的概率会导致MCU挂掉。原因是USB_OSA_ENTER_CRITICAL等宏使用的是禁止调度的函数，无法保护中断与任务的临界资源，修改为禁止中断可以解决这个问题。
请提供验证的bsp和config (provide the config and bsp)
