Renato,

could you please apply the stupid patch below (against 2.6.20, I know you 
are using it :) ) and report the result? It should show us whether the 
values 0 and 4096 (which can be seen in your hid parsing debug dump) are 
correctly passed from HID to input, or they are garbled inside the hid 
layer somewhere already.

Thanks.
