I heard it's not possible to pass > specific USB ports but instead the whole PCI has to be passed Yes, you can pass through a whole USB controller, not its individual ports. In practice therefore you will probably need at least two USB controllers on your system, unless it is headless. > and it seems to be as complex as it sounds: I think the complexity is overstated in the article. A better (although slightly out-of-date) guide is https://wiki.freebsd.org/bhyve/pci_passthru. In particular I did not have to recompile the kernel or remove the xhci driver. As far as I remember all that is necessary was to add three lines to /boot/loader.conf: hw.vmm.amdvi.enable="1" # AMD only: delete this line if you have an Intel processor. pptdevs="10/0/3" # Change 10/0/3 to the address of your USB controller. vmm_load="YES" # Load the bhyve kernel module on boot. [There are some other caveats, for instance you may need to enable directed i/o virtualization in your BIOS.]help
