![Ubuntu 22.04LST 上不断出现 USB 连接和断开连接的声音](https://linux22.com/image/1188950/Ubuntu%2022.04LST%20%E4%B8%8A%E4%B8%8D%E6%96%AD%E5%87%BA%E7%8E%B0%20USB%20%E8%BF%9E%E6%8E%A5%E5%92%8C%E6%96%AD%E5%BC%80%E8%BF%9E%E6%8E%A5%E7%9A%84%E5%A3%B0%E9%9F%B3.png)
我有一台 Alienware Dell R4,我在 Windows 10 旁边安装了 Ubuntu。有持续不断的声音,似乎是电源充电器连接/断开的声音。不过我不认为我遇到了问题。
我运行过“dmesg”命令几次,每次听到声音时都会出现这些行。显然它来自 USB 2-2:
[ 1546.508919] usb 2-2: USB disconnect, device number 3

我对此进行过研究,但目前尚无结果。
非常感谢您的任何线索。声音出现的频率很高。
更新了每次出现该声音时我收到的 dmesg 文本。看起来是来自 USB3。仍在研究中。
谢谢你!
