Help: OWL boot when Witch plugged to host via USB hub

Hey friends,

New Witch user here. For the purposes of my rig, I am needing to have the witch routed to my husband host via a usb hub (the one I am using is the electron Overhub). However, when doing this, the witch starts in boot mode. Is there any advice anyone could offer on how to get the witch running properly through a hub?
