Centos 7.5 上 /var/log/messages 上的奇怪 USB 設備連接消息
我在執行 CentOS 7.5 的專用伺服器中看到一些奇怪的 USB 設備連接和斷開消息。這些消息幾乎每天都會出現，但它們不會在每天的同一時間出現。消息的時間是隨機的。我已經聯繫了我的專用託管服務提供商，他們說他們不知道此消息的原因。他們已確認沒有 USB 設備物理連接到伺服器。他們認為這是與作業系統相關的錯誤或 USB 驅動程序問題。我應該擔心這個嗎？我應該忽略這些消息嗎？任何幫助表示讚賞。謝謝！
我的作業系統詳細資訊如下：

這些設備是 Supermicro（和其他伺服器品牌）伺服器內置 IPMI 提供的 USB 集線器/埠，用於通過 IPMI Web 界面或 Java 控制台連接虛擬 USB 設備。這意味著主機板有問題。應該更換它。當最壞的情況發生時，您不希望 IPMI 不可靠。
