硬件：MSI Stealth 笔记本电脑配备 Intel I7 CPU 和 nvidia RTX 3080。
操作系统：Ubuntu 20.04.3-内核 5.13.0-30-generic
其他人也报告过这个问题，并给出了不同的修复建议，但对我来说都不起作用。就我而言，这个问题一开始是间歇性问题，在多次重启后会恢复正常状态。在最近的升级之后，这个问题就成了永久性问题。
我不认为问题与 BIOS 或硬件有关，因为我可以启动到实时 USB（Ubuntu 20.04.3 LTS - 内核 5.11.0-27-generic），并且所有 USB 端口均可用。以下是系统状态当 USB 端口可用时

一些在线建议的修复涉及 /sys/bus/pci/drivers/xhci_hcd/ 中设备的解除绑定/绑定，但这对我来说不起作用。
任何帮助都将不胜感激。没有 USB，我的笔记本电脑就成了一块砖。
谢谢
