[Xen-users] Pass through multiple USB Devices

So, now that I''ve determined that PCI pass-through requires VTd,
I''m looking into USB pass-through to get serial ports from my dom0 to
my HVM domUs.  My first question is this: has there been any progress made in
the current stable versions of Xen on passing through multiple USB devices?  How
about the unstable versions?  Since my domUs will be Windows-based,
it''s annoying to have to give up the absolute mouse point support
(usbdevice=tablet) just so I can forward a USB device through.  Furthermore, if
I have multiple USB-to-Serial devices attached to my dom0 that I need passed
through to my domU, can I do that?

I''ve also seen a couple of posts that allude to some sort of patch for
the Xen code that enables multiple USB pass through - can anyone confirm this
and point me in the right direction?

Thanks!
