iPhone Tethering DIR-860L B1

Is it possible to tether an iPhone to DIR-860L B1? Using latest developmental with Luci installed. I simply can't find any instructions besides old OpenWRT stuff that doesn't seem to mirror what I have here.

Tethering from USB (similar to this Hak5 Setup) or as a WiFi client ?

I want to tether via usb for a hotel traveling router.

Take a look there, maybe it will lead you in the right way:
