我有一台新电脑，几天后启动时间过长。我检查了 dmesg，发现了这个美妙的信息：
[ 3.523786] usb 3-7: new high-speed USB device number 3 using xhci_hcd
...
[ 8.910825] usb 3-7: device descriptor read/64, error -110

[ 67.782730] usb 3-7: device not accepting address 6, error -71
[ 67.785775] usb usb3-port7: unable to enumerate USB device
请注意，这是启动时的输出，当时除了电源和以太网电缆（甚至没有显示器）外，没有任何东西连接到计算机。
我在 /sys/bus/usb/devices/3-7 中没有看到任何 usb3-port7，但检查接近的 3.6，它是：
5702:048d（产品编号：供应商编号）
如果我用谷歌搜索，它就会显示一些 rgb 照明控制器。
并且 usb3 是 0002：1d6b，其中 IIUC 只是一些 usb 集线器。
现在。我没有任何 RGB 照明，我打算拥有它。我被引导去调查这个问题：a) 启动时间更长 b) FPS 神秘下降，这在 Linux 和 Windows 上都会发生。行为不当的 USB 可能会导致中断或某些可以解释这一点的东西（也许）。
有人可以建议该怎么办吗？
编辑：发生这种情况时的上下文；这只是相关性，但我正在调查 FPS 下降并重新验证 windows 中的行为，碰巧 windows 也已安装（由供应商发货安装），我想我在离开时单击了 windows 中的更新。有可能，它在 gigabyte 台式机上更新了某些内容，现在由于某种原因它在 linux 上不再起作用了。
