Abstract
A standalone virtual device driver that is not a mouse driver replacement or a mouse minidriver examines mouse data packets received from the mouse hardware for data packets that are obviously or likely to be faulty. When such a data packet is detected, the virtual device driver also removes the suspected faulty data by returning a null mouse packet to the mouse driver in its place. The virtual device driver may also initiate resynchronization procedures or reset the mouse hardware if necessary.
