If the renesas usb 3.0 host controller follows XHCI spec, then EDKII XHCI
driver could be used to manage it.

Hello everyone. Just wondering if default builds of ovmf form
http://www.tianocore.org/ovmf/ has support of renesas usb 3.0
controller and if we can enable it in custom build.
First, please don't use the binary from <http://www.tianocore.org/ovmf>.
It is incredibly old (Feb 9 2014). Instead, I recommend <
http://www.kraxel.org/repos/> for anything "bleeding edge".

(Unless you are willing to build your own OVMF, of course, in which case I
recommend that instead).

Second, OVMF includes the "MdeModulePkg/Bus/Pci/XhciDxe" driver. I assume
you assign your Renesas host controller to the virtual machine; is that
right? If your host controller is supported by XhciDxe otherwise (IOW it
would work in a purely physical setup), then I think it should work with
device assignment as well.

CC: Gerd for owning kraxel.org and for USB knowledge
CC: Feng for maintaining XhciDxe
CC: Alex for any possible quirks with USB host controller assignment
