Not sure that I totally understand the question.
The webcam output from the ATEM Mini Pro operates as a USB Video Class (UVC) device which sends compressed video data over USB to a computer (the host in USB terms).
USB hubs are generally connected to a USB host (the computer in this case). So you could probably use a USB hub connected to a computer and connect the ATEM Mini's USB output to a USB port on the hub. But this isn't going to get you any additional functionality; the behavior would be similar to if you connected the ATEM Mini to the computer directly.
The ATEM Mini Pro only operates in USB host mode for local recording, when writing H.264 encoded video to an attached USB disk. In order to send out uncompressed video (such as HDMI or DisplayPort video) over a USB port requires something called USB Alt Mode, which uses some of the USB data lanes to send video data (leaving the other lanes for regular USB data):

Support for USB Alt Mode is an optional part of the USB specification, and I don't believe the ATEM Mini supports any of the Alt Mode specs.
