I am seeing some strange USB device connect and disconnect messages in a dedicated server running CentOS 7.5. These messages appear almost every day, but they do not appear at the same time every day. The time of the messages is random. I have contacted my dedicated hosting provider and they say they do not know the reason for this message. They have confirmed that no USB devices are physically attached to the server. They think it is OS related bug or USB driver issue. Should I be worried about this? Should I ignore these messages? Any help is appreciated. Thank you!
My operating system details are below:
