Hi,

Just wanted to update:
the unbind method worked with some kernels, but not all.
In one device&kernel, after doing the unbind, on entering event, the
device immediately has boot itself !

Yet , luckily, I have found another method which works:
   chmod 777 /dev/input/eventX
   rm /dev/input/eventX
It works :) !

Thanks,
Ran
