Hello everybody,

I try to doing USB pass-through with XEN hypervisor using libvirt and i get the following error:

# virsh attach-device c6test /tmp/usb_device.xml error: Failed to attach device from /tmp/usb_device.xml error: unsupported configuration: unsupported device type

Looking at src/xen/xend_internal.c, I see that only attach/detach of PCI host devices is implemented. There is currently no support for virDomainHostdevSubsysType of VIR_DOMAIN_HOSTDEV_SUBSYS_TYPE_USB. Patches welcome :). Regards, Jim
