Abstract
A method and apparatus for enabling the use of two or more pointing devices with a computer, where the pointing devices generate data packets of different sizes. The maximum size of the data packets generated by the pointing devices is determined. Any data packets received from the pointing devices which are smaller than the maximum size have additional bytes added to increase the size of the data packet to the maximum size. Thus, the computer receives the same size data packets from all of the pointing devices, facilitating the use of multiple pointing devices.
