I am having the same problem, but only after resume from suspend or hibernate. I first thought it was a bluetooth problem, as my bluetooth mouse stops working after a minute or so after resume. However, both the bluetooth adapter is gone (bluetoothctl says "No Default controller"), but also ordinary USB mice will not work.
It seems that HCI dies, and the kernel decides to remove everything else as well. Touchpad works however. I am running 18.04 alpha with 4.16rc3 (4.16.0-041600rc3-generic) mainline kernel. Hardware: Lenovo Thinkpad E580. Full syslog output. BTW: "MX Anywhere 2" is a BT mouse, not a keyboard. Not sure why it is registered as such.
