[18:34] Ran into what sounds like a similar issue.
3 x Surface Two Pro 2s
3 x Rosewill 4 Port Super Speed USB 3.0 hub (each plugged into Surface Pro 2 USB port)
3 x Microsoft 5000 keyboards and mice
3 x WD "My Passport Ultras"
One mouse acted as described in "Sticky/jumpy mouse cursor"
Swapped hubs - problem followed hub.
Problem may have been USB 3.0 noise related.
