  Keyboard and mouse not working after update to 15.04

Status in linux package in Ubuntu:

Bug description:
  After turning on the system, mouse pointer is not visible and first
  key press on keyboard is ignored.

  When I press mouse button (left or right), mouse pointer appears and I
  can control it, but when I leave it for few seconds, it disappears

  As for the keyboard, the first key press is ignored (e.g. when I try
  to type "zone", only "one" is visible on the screen because the first
  key is ignored) - this behavior repeats itself after few seconds of
  not pressing any keys.

  My keyboard has backlight option and when I turn it on, the light
  flickers and disappears when the keyboard gets "disconnected".

  Disconnecting and connecting again mouse and keyboard makes the issue disappear - from that moment on, both mouse and keyboard work like a charm (until reboot).
