If the Pi and Vero4K are both running the latest OSMC (2017.12-1), you might have some success using a newly-added feature in the kernel: USB-over-IP (usbip).
I’ve not tried it myself yet but I found instructions on its use here. Go to the post from “secretagent” at Thu Jul 12, 2012 11:40 am. Start from "Then install usbip: ", since you don’t need to build anything.
If you try it, let us know how you get on.
