I'm specifically looking for a device that has four USB 3.0 controllers
that can be passed through individually to VMs via KVM. That way each port
has the full 5GB/sec USB 3.0 speed all to itself in each VM (up to four).
If you look at the RocketRaid 1144c/1144d, the StarTech PEXUSB3S44V or the
Sonnet Allegro Pro you will see that they all have four usb controllers
each behind a ACS compatible bridge. None of them work properly for
individual passthrough under KVM in my experience.
