The last 2 weeks, I fight vs this with Centos 5x:

1; U MoBo must be able to support IOMMU/VT-x and u must warranty that
is avilable searching the words "I/O Virtualize Enable" something like
this went u run xm dmesg.
2; Example with centos 5x, I enable PCIBACK as module, is not
available on the kernel.
3; setup /etc/modprob.conf
4; reboot and see that pciback is load and that my usb ports where
load by pciback.

run xm pci-list-available

U must receive the id ports u hide from your Dom0, if not u better fix this.

Once u hide the ports from dom0, once u run this command:

lspci -vvv -xxxx, search for them and u will see that the driver say: pciback.

I try with xen 3.4.x, 4.1.1 and works.

In my case USB .2.0 didn't work because the bios had some issue, with
"non-page-aligned MMIO BAR" the fix didn't work, the people from the
list  told me that was the BIOS, usb 1.1 on windows xp pro sp3 works,
with 3 different USB memory sticks, even with a HASP usb key, with win
7 some usb works other don't nut the hasp key did'nt work.

No USB 2.0.

Them, good luck!!!
