Likely, but not necessarily.  It would sure be interesting to poke
around with adb shell, if supported.

Right, so "hid" in the interface mode list was really HID.  I just
assumed it was a function name for the web service.  Well, then we don't
know which of these modes support the web service or not.  It's tempting
to guess that it always is present regardless of network function type.
But then again, it might not be.

Yes, the HID descriptors look weird and I don't understand what they are
supposed to be used for.  Some sort of vendor specific monitor
application support, using HID reports maybe?
