如何禁用有故障的 USB 端口？

Question

我使用的是 Ubuntu 20.04，我的计算机的网络摄像头已经出现故障一段时间了。在睡眠/挂起时，我看到了很多usb 1-8: device descriptor read/8, error -71错误。我查看了dmesg输出，发现相机不断断开/重新连接。输出如下dmesg所示：

我认为这也会产生下游影响：lsusb运行需要十秒钟，而我插入的 USB 设备有时需要几分钟才能被识别。我打算发送此信息以查看端口本身，但与此同时，如何禁用该端口？我已经尝试过此问题中概述的解决方案，但问题之一是在 中/sys/bus/usb/devices/，故障 USB 设备的符号链接和文件夹有时存在，有时不存在，因此我无法使用tee基于 - 的解决方案，并且udev基于的解决方案不起作用。
