Try to install "AI Gear 2" then promptly uninstall it. The
unknown device, as near as I can tell, should be resolved
once AI Gear 2 is installed. On removal, it is possible the
driver will be left there, and the unknown device will then
be known.
The ATK thing is an Asus identifier, which means it is
created as a means of passing something from the BIOS
to the OS. My guess is, that AI Gear 2 is what uses
that interface. The unknown device is not real hardware,
but a virtual device that Asus made and passed via
an ACPI table entry.
