周一下班后,我像往常一样关闭了笔记本电脑(Dell Vostro 15 3000),第二天回来时,我发现电脑已关闭(电池没电),我不得不重新启动。从那时起,2 个 USB 端口都无法工作:
- 我试过的 USB 鼠标都没有任何反应,事实上插入后它们甚至都没有打开。它们在其他机器上工作正常。
- 如果我通过 USB 连接手机,它确实会在两个端口上充电,但系统无法识别它
我之前使用的是 Ubuntu 20.04,我以为升级可以解决这个问题,但结果什么也没改变。我现在使用的是 Ubuntu 22.04.2 LTS (5.14.0-1057-oem)
这是 lsusb 的输出,无论插入任何端口,此输出都不会改变:
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001

003: ID 0cf3:e009 Qualcomm Atheros Communications Bus 001 Device 001:
ID 1d6b:0002 Linux Foundation 2.0 root hub
当我插入或拔出设备时,dmesg 也没有发生任何反应:

重启电脑无法解决任何问题(即使是暂时的)。在启动过程中,鼠标确实打开了,但一旦出现 grup,它就会显示为关闭状态
任何想法?
