@大法师 对，更新了之后也没变化，无法运行指运行相机相关程序时会报USB uvc相关的错误。

@大法师 按照您的流程试过了，没有任何变化。建议您还是得拿相机试一试。另外我又发现，Pi4B的USB3.0的口，底部那个才有我们讨论的情况，上面那个口上电能识别到USB3.0，但是实际无法运行。

@大法师 好的多谢，那么请问那个到了内核之后再加载驱动，可不可以理解为我再写个脚本开机之后手动insmod来加载USB驱动呢？如果是的话我应该去哪里找到这个USB驱动呢？

@AugustRobot_Zou 牛的，种草了

我在最后重新插拔了一下，在日志最后有体现。

@AugustRobot_Zou 效果怎么样？我们给无人机用怕距离太短了。

@george 关闭uboot下USB设备的注册需要改UBOOT代码吗？还是直接上电的时候进uboot改一下就好了？

@george 好的我试试

@jack_admin 稍等我明天看看

补充，同样的系统、设备和线在香橙派5上试验过，没有出现过类似问题。

系统：coolpi官方提供的Ubuntu20
USB设备：Intel realsense d435深度相机

问题十分稳定，每次开机都是识别为USB2.0设备，这是sudo cat /sys/kernel/debug/usb/devices命令执行后有关项目的输出：
开机后：

尝试过一些重置USB设备的方法：

Linux从命令行重置USB设备
uhubctrl重启usb设备

都没有效果，复位之后还是识别为了usb2.0。

后来尝试问微软的chatgpt，得到以下回答：

That sounds like a firmware issue. It could be that your firmware detects the device as USB 2.0 at an early stage and the USB 3.0 features are activated later in the boot process. If a device is already connected, it won't change to USB 3.0 speed later on.

事实证明它是对的，我尝试先打开电源再插数据先，果然可以被正常识别为USB3.0设备。
目前我还是无法解决问题，不知道大家有没有什么看法。
