Here is my post issued again from the beginning in some sort of logical order I hope, with additional information as suggested by George Dunlap.
I am having trouble getting PCI Passthrough to work from Dom0 to DomU
I am using Xen 4.6 with CentOS kernel 3.18.34-20.el7.x86_64 on a Dell Poweredge T430.
When I plug in a device to the USB port, nothing happens. I am Watching /var/log/messages in the DomU. Nothing
Here is my lspci on the Dom0 filtered to show USB and PCI devices

Here is my lspci on the DomU
00:00.0 USB controller: Intel Corporation Wellsburg USB Enhanced Host Controller #2 (rev 05)
Prior to starting the DomU I issue command:
xl pci-assignable-add 00:1a.0
xl pci-assignable-list
0000:00:1a.0
0000:00:1a.0
So this is OK
Now for the config file for the DomU

# two ethernet devices, one for the network, one for the Eumetcast receiver
vif = ['mac=00:16:3E:00:00:35, bridge=xenbr5', 'mac=00:16:3E:00:00:36, bridge=xenbr6']

I have pcifront showing as a module in the DomU and the usb shows in dmesg

Can anyone help sort this out, so I can get USB devices to be recognised. I want to plug in my Eumetsat Dongle for receiving Weather Satellite images.
