USB problem with keyboard

  Hi All,

    I changed my old multimedia keyboard (Genius) to a new one
small and simple keyboard.  I thought the problem was
the dirty on the keyboard so i clened but it's still not working
well ( it's not showing all keys pressed or sometimes repeat the
last key pressed).

    This problem was started when I updated my box, but
I had other old problem that I ignored for a while 
My usb mouse and my no-break APC random disconnect and reconnect
sometimes per hours
