Ubuntu 22.04 LTS 无法完成启动，反复尝试连接USB 1-8端口求助

我目前用的是Ubuntu 22.04 LTS系统，之前因为有一块外接硬盘需要额外供电，特意接了个带电源的10口USB集线器。等相关操作搞定后，我把外接硬盘和USB集线器都拔掉了，然后重启了系统。

结果重启后系统卡在启动流程里，一直在反复尝试连接USB 1-8端口。我用dmesg|grep usb命令查了日志，输出如下：

[    2.514991] usb 1-8: new full-speed USB device number 4 using xhci_hcd

大概到设备编号22的时候，我按下Ctrl+C才进入正常命令行，之后系统能正常使用。我又用lsusb查了当前USB设备列表：

Bus 002 Device 002: ID 0781:55af SanDisk Corp. Extreme Pro 55AF
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 003: ID 31b2:0010 KTMicro KT USB Audio
Bus 001 Device 002: ID 046d:c52b Logitech, Inc. Unifying Receiver
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

最终解决办法 #

后来看到用户YtvwLD的一条实用评论，提示这些错误信息和蓝牙适配器有关。我试着移除了系统里的蓝牙适配器，重启后问题就彻底解决了！
