Yes, We can have a black list instead of white list. Are you planning to submit changes?
Thanks,

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.

Alexander
