I am trying to passthru an 3.0 USB contoller card (this guy here: https://www.amazon.de/Logilink-PC0057-Express-Schnittstellenkarte-Karte/dp/B005GUQV1Q) into one of my bhyve virtual machines.
I am basically following this guide.
My USB controller card works on the host and is listed as follows via

One thing I observed: In the diff of
pciconv -lv before and after installing the USB controller card, there was one additional change. The full diff looks as follows:
