Probably not.

Documentation of how to create a UIM (USB Interface Module) has not been uploaded anywhere so we cannot make a EHCI UIM for USB 2.0 or an XHCI UIM for USB 3.x.

I suppose one could try reverse engineering the OHCI UIM for USB 1.1 then create a UIM for EHCI or XHCI.

You can find some documentation of the USB Interface Module (UIM) in USBPriv.h but that doesn't have everything required.
