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.

Regards,

Alexander
