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..
