Solved PCIe USB with individual controllers

[jbo@]

Some time ago, somebody on this forum posted a link to a PCIe card which provided four (?) USB-A port. The important part being that each of those ports had it's own USB controller which from a practical perspective would mean that one can pass through a "single USB port" to a bhyve VM.

Does anybody with better memory or better forum search skills remember what card that was?

That is not correct. They make cards for virtuilization that use seperate PCIe addresses for each controller onboard.

I am using these with bhyve for USB passthrough. It has 4 independent controllers. Usable for 4 VM's.
So 1 USB3 port passed to each VM.

They also make a two channel / four port version.
Not cheap. What in server world is.
