Thing is, there is no difference in what the HMC software (or firmware,
even) sees between an internal and an external USB device. It can't see
what you can see, i.e. the routing of the wire (if any) to another place
inside the case, or to a jack that is accessible from outside. So it seems
only reasonable to report on all USB devices it sees.

If it reports only on what *should* be there, and *should* be internal,
then obviously you may receive an incomplete report on what *is* there.
Seems to me you received exactly what you needed: you were surprised at the
reported presence of a device that you hadn't known about, you made
inquiries, and got the answer.
