I noticed this problem because my wireles KB/Mouse combo became nearly unusable after upgrading from 17.10 to 18.04. I'm seeing the high CPU consumption as reported above and the dell HID messages as reported above. Also, if I unplug the transceiver for my KB/Mouse it stops working until I reboot.
My machine is a Dell XPS 15 9560. So, also a Dell, but a very new one.
Downgrading to kernel 4.13 has alleviated the symptoms.
