Re: usb devices passthrough in bhyve

Hello.

I have a situation similar to yours. This is my USB controller integrated
with the motherboard (INTEL AORUS PRO) :

00:14.0 USB controller: Intel Corporation Cannon Lake PCH USB 3.1 xHCI Host
Controller (rev 10)

I have attached a lot of USB disks to that USB controller,but I never
reserved it, placing it on the /boot/loader.

Let's take this disk for example,that's attached there :

=>        40  3907029095  da5  GPT  (1.8T)
          40      532480    1  efi  (260M)
      532520        1024    2  freebsd-boot  (512K)
      533544         984       - free -  (492K)
      534528     4194304    3  freebsd-swap  (2.0G)
     4728832  3902300160    4  freebsd-zfs  (1.8T)
  3907028992         143       - free -  (72K)

If I want to use it with bhyve,I do :

bhyve-lin -S -c sockets=2,cores=1,threads=1 -m 4G -w -H -A \
-s 0,hostbridge \
-s 1,ahci-hd,/dev/da5 \

Easy,isn't it ? But this technique works only with the disks. If you have a
different kind of device,you should use an additional USB to PCI
controller....
