System and method for synchronization of pointing devices with different data packet sizes

摘要

A system enables the use of multiple pointing devices which generate data in different protocols by determining which is the largest of the protocols used and converting data packets from the other pointing devices into this protocol by adding bytes as required. The operating system 58 running a program 60 requires a single size input which is provided by the keyboard and auxiliary device controller (KBC) 50 which receives signals from pointing devices 52 and 54 which can have different protocols. The KBC can send a command to each pointing device to indicate what size of data packet it will produce and then analyse these signals to select the maximum data packet size.
