Strangely, seabios supports booting from usb-uas with usb-ehci:
https://drive.google.com/open?id=0B50PCxfm5KU1dUFTUG9HU0pEcXc
and usb-bot with nec-usb-xhci:
https://drive.google.com/open?id=0B50PCxfm5KU1QnVzdTBIdEFzZW8
but not usb-uas with nec-usb-xhci:
https://drive.google.com/open?id=0B50PCxfm5KU1Z0t1akNXaVZZLTQ
This makes me wonder if it is just a missing feature of a bug.
Btw, not sure if it's relevant, booting usb-uas is not at all
supported in ovmf: https://github.com/tianocore/edk2/issues/85

I meant "or" instead of "of".

Sorry, I forgot to mention that I am using qemu 2.5.1 and seabios 1.9.2.
