This rule actually was denied upstream so it's carried as an Ubuntu
patch. Upstream prefers that hid2hci be modified to take command line
arguments before accepting this type of patch.

It looks like for some reason or another the rule doesn't work with
newer udev versions. Can you try the attached rule instead? If that
works out, we can at least put that together as an Ubuntu SRU until the
device arguments get added to hid2hci.
