Re: [Xen-users] How to pass more then one USB device to HVM guest?

[Casey DeLorme <cdelorme@xxxxxxxxx>]

Alternatively you may also be able to add additional usb devices at runtime with "xl usb_add".

If it's anything more than a keyboard and mouse though you may want to investigate PCI Passthrough, since the HVM qemu-dm only yields USB 1.1.

This fellow posted something about a patch for the xm toolstack but I didn't give it a thorough read and I saw no code submitted:

If you're not bound to xl, I'ld try using xm instead.
