I am not sure if the PS/2 code is misbehaving though.. -- regards, Balaji Rao Dept. of Mechanical Engineering, National Institute of Technology Karnataka, India -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
