Now I understand, that makes sense.
BTW I think there actually might be devices which won't be claimed neither
by hid-input nor hiddev - I mean devices with
hid->collection[i].type == HID_COLLECTION_PHYSICAL &&
!IS_INPUT_APPLICATION(hid->collection[i].usage)
for every possible i . Not a big issue, but probably might need fixing one
day.
