Before I start the guest VM the flash drive is not in the list. Right
after shuting down the guest OS it appears:

pcib1
  pci1
    sdhci_pci0
pcib2
  pci2
    iwn0
pcib3
  pci3
ehci1
  usbus1
    uhub1
      uhub3
        umass0

As you can see it's under "ehci", it looks that my USB3 controller is
fully USB2 backward compatible and work with "ehci" driver. I tried (as
Trent suggested in this thread) to recompile the kernel without "xhci",
and nothing changed, still behaves exactly the same way..
