[Bug 1454450] Re: Bluetooth mouse laggy and erratic

[Allan Brighton]

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:
