I am seeing this with a Logitech Bluetooth Laser travel Mouse on Ubuntu-16.04. (The system is set to not sleep or suspend.)
The fix mentioned above seems to work: sudo modprobe -r btusb sudo modprobe btusb Here is some output from dmesg: [ 11.035464] vboxdrv: Found 8 processor cores [ 11.053922] vboxdrv: TSC mode is Invariant, tentative frequency 2712000012 Hz [ 11.053924] vboxdrv: Successfully loaded version 5.0.16_Ubuntu (interface 0x00240000) [ 11.058160] VBoxNetFlt: Successfully started.
