[PD] hid without polling

[Peter Plessas]

Hi list,

i have an endless rotary encoder (Griffin Powermate) which i want to use 
along the [hid] external. Since the encoder only gives a relative value, 
it is very important to know, when those relative changes occur. I 
wonder if there is a way to get the values from the [hid] without 
polling it. Or is there some basic concept behind it which has to poll it?

Any ideas are very welcome!

Peter
