EHCI / XHCI Emulation in HVM Guest

Hi,

I have been using xen 4.4 to emulate EHCI/XHCI in Ubuntu HVM Guest. I have specified usbviersion 2 for EHCI in HVM config file.
However, I am unable to see UHCI / EHCI emulated controller in HVM Guest. If I do not specify usbversion in HVM then I can see UHCI emulated controller present in HVM Guest.

Is this a limitation of Xen 4.4? Xen 4.5 will come up with complete Emulation of EHCI / XHCI? If yes, then May I know tentative date of Xen 4.5 Release?

As I have to run multiple HVM Guest OSs with EHCI and XHCI, so I can have better USB performance.

I am looking forware to your response. And also let me know if you need amy more information.

Thanks in advance.
