Mouse freezing

Hi.
My mouse is always turning off/on. I think that it is the problem of the USB port's because all my mouses do that.
But if I stay like 1/2 weeks without using the mouse, when I use it again, it work's perfectly. But when I use the mouse for long periods of time, it start's failing.
It happens with almost all the mouses.

Can you tell me how to solve the problem, please? I can't play.
