我使用 Ubuntu 18.04 很长时间了，从来没有遇到过死机问题，直到上个月才遇到这个问题。但在指责 Ubuntu 之前，我想确定哪个才是真正的问题。
这些是我迄今为止尝试过的方法。1. 我在一篇文章中看到，鼠标和/或键盘冻结的原因可能是 USB 端口中有很多灰尘。所以我清理了 CPU 两次。第一次确实有灰尘颗粒，可能会形成厚厚的卷状物。第二次我使用真空吸尘器排气装置清除 SMPS 和处理器任何角落的所有灰尘颗粒。我还用高压空气清洁了 USB 端口。
- 我移除了鼠标和键盘并尝试重新连接，但仍然无法被检测到。
在观察过程中，我发现，当我点击 stack overflow 的一个链接时，我的鼠标和键盘都冻结了，但网站在大约 5 秒后仍能加载而不会冻结。因此，这可以得出结论，问题不在于整个操作系统，而在于 USB 设备。
我仍然认为这可能是 Ubuntu 的问题，因为鼠标和键盘不可能同时出现问题。在硬重置系统后，两者都可以正常工作一段时间。所以我查看了系统日志。以下是消息，我不明白出了什么问题。

谢谢。
答案1
这：
kernel: [37450.521244] usb 1-1.4: reset low-speed USB device number 31 using ehci-pci
kernel: [37452.337312] usb 1-1.4: reset low-speed USB device number 31 using ehci-pci
kernel: [37456.478074] usb 1-1.4: USB disconnect, device number 31
表示端口号 4 上的 USB 设备断开连接，这可能是鼠标或键盘停止工作的原因。至于系统本身，它看起来正常，并没有像您所说的那样冻结。
造成这种情况的原因要么是新内核对鼠标/键盘没有很好的支持，要么实际上是硬件问题。
请尝试启动到较旧的内核。此问题发生之前安装的内核，然后查看是否存在此问题。如果存在，则可能是硬件问题，无论是鼠标/键盘、USB 端口还是控制器。
为了缩小范围，请限制连接的 USB/HDMI 设备（扬声器、麦克风、耳机、显示器、USB 驱动器、鼠标/键盘等），如果有多余的鼠标和键盘，最好尝试更换不同的鼠标和键盘。断开 USB/HDMI 硬件和电缆，然后逐个重新连接，并连接到不同的端口，直到找到有故障的端口并将其更换为新的端口。
注意：
low-speed USB device通常是指鼠标或键盘，reset low-speed USB device最有可能是指由于 USB 或 HDMI 电缆或设备故障而导致电信号故障。
这意味着最有可能的是鼠标和/或键盘有故障，这很常见，只需更换它们即可解决，或者主板上的 USB 端口/控制器有故障，这并不常见，但需要更换主板。
