I have the same problem with the mouse.
Occasionally when I boot up the windows the mouse doesn't works.
I pull out and plug in and it works again.
I tried to find some signs as what could cause it, but it does absolutely randomly. For a week doesn't do, then the next week it does 2,3 or even more times.
The strangest part is that I had the same problem with my old computer. Now I have a brand new one, and still does.
It's really annoying!!
