[SOLVED] Repeated Log Message about Reset Low-speed USB Device Using xhci_hcd

I have been seeing syslog messages for a while with the following message:

reset low-speed USB device number 4 using xhci_hcd

I have found the culprit and wanted to share my fix here for anyone else who runs into this. The problem was located in the server's IPMI Virtual Keyboard and Mouse. The way to diagnose this is to look at the output of lsusb and lsusb -t. You then look what USB device is at the device number in the log message (simple, I know). In the case of my problem, all I needed to do was reboot the IPMI then reboot the server. After this, I have not observed the message in the logs again. I don't know the root cause, but the IPMI had been running since the server was installed without a reboot.
