[Pkg-libvirt-maintainers] Bug#712175: me to

[Kenneth Johansson]

so I tried to attach a usb device to a running guest.

never done this before so not sure how its supposed to work but I think 
something is wrong on libvirt.
it thinks the device is on bus 0 . bus 0 is not a valid bus.

device on host
Bus 001 Device 004: ID 0cf3:9271 Atheros Communications, Inc. AR9271 802.11n

<hostdev mode='subsystem' type='usb'>
   <source>
     <vendor id='0x0cf3'/>
     <product id='0x9271'/>
   </source>
</hostdev>

attach-device networker /etc/libvirt/qemu/networker_wifi.xml
error: Failed to attach device from /etc/libvirt/qemu/networker_wifi.xml
error: unable to set user and group to '127:141' on 
'/dev/bus/usb/000/000': No such file or directory
-------------

It works if the device is added on start up in the main xml file but not 
when pu into its own xml.

never done this before on any system so not sure if I'm doing anything 
wrong but the fact that it tries to use bus 000 looks like an error in 
libvirt.
