I am unable to reply to Stefan for some bizarre gpg issues...

But just fyi, this sounds like the same issue as the phison controller from a
different brand reported below, so it sounds more widespread than just this
particular adata model.

The reported didn't provide the device id, though, so we don't have a viable
patch for that product just yet. Perhaps we could add the vid:did to some of
the messages to help shorten the report-quirk cycle.
