Basicly you have two options:

1. Xen PCI passthrough
2. Xen USB passthrough (http://wiki.xensource.com/xenwiki/XenUSBPassthrough)

If the guest is HVM (=Windows), then you need to have Intel VT-d (IOMMU) support
in the motherboard chipset for the PCI passthrough to work.

If the guest is Linux PV (paravirtualized), then you don't need VT-d or 
anything special
for the PCI passthrough.
