I just received a used wico trackball and performed the mouse hack while at work (shhhhh) but whe I brought it home and hooked it up the mouse does not respond well with it, I increased the mouse speed still no good response, when you spin the rollers fast the mouse does not move until they start to slow down quite abit. Is there something I could have done wrong or is there something I can easily fix without trashing the used ball and buying new...
