Hmm, might be a firmware bug, but this also might mean it can detect
more fingers then previous versions, and sends a new packet type when
more then X fingers are present, we should probably end a mail to
our contacts at elantech about this. Since you've the hardware I
assume you will be sending such a mail ?
