Just checked. The upstream Kernel versions: 4.1.0-040100rc7-generic #201506080035 and 3.19.8-031908-generic #201505110938 from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D don't seem to exhibit this problem. Will try to do a git bisect between "355957e Linux 3.19.8" and "a52caa6 UBUNTU: Ubuntu-3.19.0-20.20" and see what that turns up.

Other USB-devices (I tried it with several USB Flash drives) continue to work on the USB 2.0 ports. The USB 3.0 port on the laptop does not show this behavior, i.e. a human interface device never stops working. Unplugging and replugging the mouse does not reactivate it. The mouse works again for a random amount of time after a reboot or a wake-up from suspend to RAM. When the mouse stops working the respective /dev/input/mouseX device does not produce any output either. The touchpad, that is connected via PS/2, does not show this bug.
