I removed the mouse, cleared dmesg, loaded ohci_ inserted mouse in one of the 
ports, moved it, lots of jerks. It was good for a couple of seconds, then it 
hangs&is jerky, than was ok for a while.
 Sometimes it is good for several minutes before becoming jerky - and there is 
nothing I know of to make it appear. It just happens and goes away. Randomly 
it seems.
