Yes, We can have a black list instead of white list. Are you planning to submit changes?
I've just have implemented my first version of a time sensor. So yes (at
least the time sensor).
That's why I stumbled over that. I had to add a vendor and device ID to
those two files. I also noticed that hid-sensors(-hub) doesn't work with
combined HID devices (e.g. mouse/keyboard/sensor) and as a first
workaround I've just modified the HID-tree of my device. As I'm fairly
new to the HID stuff, I'm still in the evaluation phase (reading source
and such).
In regard to a blacklist, I don't know how to fill it. I only have the
one sensor device I've build myself (it's a spare-time project).
I think the first step would be to identify devices usable by
hid-sensor-hub, sensor_hub_check_for_sensor_page() looks like the way to
go, at least for the current state of the hid-sensor-framework.

We have not tested on sensor hubs from different vendors except few. It is possible that some vendors are using sensor hub as raw devices . We can remove vendor product ids once we have a good list for support.
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.

Subject: HID-sensor(-hub.c) and device IDs
Hello,
is there any special reason why vendor and devices IDs for HID-sensors must be listed in drivers/hid/hid-sensor-hub.c and drivers/hid/hid-core.c?
Maybe I'm missing something, but I don't think this is how HID is supposed to work.

Alexander
