Hmm, sorry, I don't understand that fully. Does that mean that the list 
is there to use the driver only with a small group of devices because 
otherwise some HID-sensors aren't usable as raw devices?

I don't know how many HID-sensor devices are already out in the wild, 
but because the standard looks fairly new, I don't think there are that 
many. And I wonder how you want to get the list larger, if nobody 
notifies that they should use hid-sensor-hub.c.

I think the correct way would be to build a blacklist instead of a 
whitelist.
