Thank you. I have the Fushicai USBTV007 plugged into a powered USB 3.0 hub.
Here's lsusb:

What's interesting is that I played around with it a little bit after I posted and I can run:
LD_LIBRARY_PATH=/storage/hyperion/bin /storage/hyperion/bin/hyperiond /storage/.config/hyperion.config.json --crop-top 0 --crop-left 0 --crop-bottom 0 --crop-right 0 --size-decimator 8 --frame-decimator 2
via SSH and it comes on and captures video from USB. It flashes black/white about every 30 seconds, but I'm not sure if that's a software issue or with the HDMI2AV. When I switch back to Kodi via USB capture, it's lower resolution and doesn't flash. I assume that's a hardware issue, I already ordered a new HDMI2AV.
