I had this idea maybe a year or two years ago, there was also another guy
[he worked on the fbuffer for bhyve] who wanted to get it done but they
were waiting on the main guy behind the USB stack on freebsd: hselasky

He was too busy to actually do any work so the project stalled.

My use case for having direct access to usb devices in a bhyve vm could
allow rapid development of USB drivers for FreeBSD by sniffing the packets
being sent over USB to the bhyve guest and reverse engineer drivers so that
we can write native drivers for common devices that aren't supported on
FreeBSD yet.

I had to put that on the back burner for a bit since there's a lot more
pressing FreeBSD issues that I am working on.

What's your use case?

Best,
