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.

After this, the laptop doesn't recognise any device plugged in to the USB ports - plugging and unplugging any device I've tried into any of the USB ports produces no response, not even dmesg entries. Strangely this also applies to bluetooth - it no longer works once USB has dropped (possibly the module is hung of the bus internally). Once this has happened only a reboot fixes it; I've not managed to find any combination of module unload/reload or suspend cycles to reinitialise things correctly.
