我在运行 CentOS 7.5 的专用服务器中看到一些奇怪的 USB 设备连接和断开消息。这些消息几乎每天都会出现，但它们并不是每天在同一时间出现。消息出现的时间是随机的。我联系了我的专用托管服务提供商，他们说他们不知道此消息的原因。他们已确认没有 USB 设备物理连接到服务器。他们认为这是与操作系统相关的错误或 USB 驱动程序问题。我应该担心这个吗？我应该忽略这些消息吗？任何帮助都非常感谢。谢谢！
我的操作系统详细信息如下：
[root@myserver ~]# uname -a
Linux myserver 3.10.0-862.14.4.el7.x86_64 #1 SMP Wed Sep 26 15:12:11 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
[root@myserver ~]# cat /etc/centos-release
CentOS Linux release 7.5.1804 (Core)
我的服务器规格如下：
Intel Xeon E5 1650 V3
256GB SSD on RAID 1
2TB HD on RAID 1
我的 RAID 卡详细信息如下：
[root@myserver ~]# lspci -knn | grep 'RAID bus controller'
04:00.0 RAID bus controller [0104]: LSI Logic / Symbios Logic MegaRAID SAS 2108 [Liberator] [1000:0079] (rev 05)
下面是我在 /var/log/messages 中看到的消息示例：

答案1
这些设备是 Supermicro（和其他服务器品牌）服务器内置 IPMI 提供的 USB 集线器/端口，用于通过 IPMI Web 界面或 Java 控制台连接虚拟 USB 设备。这意味着主板出了问题。应该更换主板。当最坏的情况发生时，您不希望 IPMI 不可靠。
