usb 3-4:设备描述符读取/64，错误-71 -但设备不存在

Question

这是我的第一个问题，我对Linux和Ubuntu非常陌生，所以请不要对我太客气。

从昨天起，我一直在努力想办法解决这个问题，我的情况似乎和其他的不同。或者至少我认为是这样。

下面的输出在syslog和kern.log中处于循环状态

当我检查usb3-port4中的设备时，它并不存在于lsusb和“/sys/bus/usb/设备”中。

当我将usb3中的授权文件更新为0时，这些消息将被停止。但我所有的USB端口都无法使用。

/sys/bus/usb/devices/usb3$ ls authorized 
authorized

当我检查usb设备命令时，我在Bus3和端口4上找到了我的联想Bus3，但是这台相机工作正常。

在lsusb -t中，摄像机似乎位于端口5。

我试着禁用它，但将授权文件更新为0，但这也没有帮助。

我想我的解释完全错了。救命啊！

谢谢！！
