I have a USB controller I wish to pass to a HVM guest.  More
specifically a WindowsXP HVM guest if that matters.  I have iommu=1 on
the hypervisor line in grub.cfg as well as xen-pciback.hide=(00:12.2).
In the VMs config file I have the following:

pci= ['00:12.2']

Whenever the VM is started it gives the following error:

libxl: error: libxl_pci.c:794:libxl__device_pci_add PCI device 0:0:12.2 is not 

My CPU(Opteron 6128) is iommu capable.  I am using kernel from 
source with pciback compiled into the kernel.  What am I not doing that sets 
00:12.2 as
an assignable device?
