从暂停状态唤醒时出现“设备描述符”错误

Question

我目前正在努力解决我的 Kubuntu 18.04 系统问题。从 唤醒机器时systemctl suspend，屏幕打印以下几行错误：

[17823.756393] usb 8-1: reset high-speed USB device number 3 using xhci_hcd
[17829.064673] usb 8-1: device descriptor read/64, error -110
[17829.300671] usb 8-1: device descriptor read/64, error -2

每次唤醒时都会添加一些行。有时，机器会冻结，甚至无法加载登录屏幕，所以我需要重新启动。我已经在 Google 上搜索过错误，但找不到任何线索。

希望有人有想法并能帮助我。

感谢你们！

编辑：sudo journalctl -f | grep usb有以下输出：
