This needs the output of the hidpp-list-features tool mentioned earlier
in the thread so we can avoid words like "evidently" and provide
concrete proof.

But why is it needed in this case? We purposefully try to avoid blanket
blocklists. The lack of HID++ can be probed, so the device should work
just as it used to (if the fallback code works).

We should only list devices that need special handling, and the ones
that don't work once HID++ was probed unsuccessfully.
