On a laptop with Ubuntu 18.04, /var/log/syslog gets new block of the four following messages about 5 times per second:
Aug 29 19:17:17 my_hostname systemd-udevd[336]: Process 'hid2hci --method=dell --devpath=/devices/pci0000:00/0000:00:1a.0/usb3/3-1/3-1.2/3-1.2:1.0' failed with exit code 1.

They are filling up the log partition. I do not have anything plugged in any USB port. The corresponding PCI device is:
$ lspci | grep 00:1a.0
00:1a.0 USB controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #4 (rev 03)
What can be the reason of these messages? How should I correct the situation?
