Multitouch USB

Has anyone experience of using the USBHost library to get touch information from a USB infra-red touch frame? I can get the first touch, equivalent to a mouse click, but I cannot get simultaneous touches from multiple fingers. The frame is a 10-point multitouch frame from Greenspan - works fine in Windows so it is capable of this. The output from the hid descriptor example is:
