[PD] Question about hid external and polling

[Jean-Yves Gratius]

Hi,

I'm trying to retrieve infos from an Elan mutlitouchscreen  using hid 
object in puredata (on linux).

I succeeded in getting multitouch infos, but with some inconsistencies, 
so I wonder if I may loose some messages dueto incorrect  polling value ?

Is there a non polling mode giving all the incoming messages as they 
arrive ?

Thanks so much.
