Re: [Xen-users] How do you give USB to a Windows domU?
The configuration file for the domU is under /etc/xen/vm/ with the name the
same as the domU. You can update the config file, then do "xm delete <domU>"
and then "xm new <domU>" and this should refresh the configuration. You only
need to worry about pciback if you want to forward the entire PCI-based USB
controller through to the domU - this will make the USB controller unavailable
to dom0, which on most modern machines isn't a great idea as USB is generally
used for keyboards and mice these days.
