[libvirt-users] Can't plug usb device

[Jesus Urroa]

Hi
I'm trying to hotplug an usb device into kvm but the device is not attached
this is the definition:

cat kingston.xml
<hostdev mode='subsystem' type='usb' managed='yes'>
        <source>
                <vendor id='0x1131' />
                <product id='0x1001' />
        </source>
</hostdev>

the attach and detach commands

virsh attach-device ShadowFax kingston.xml
El dispositivo fue asociado exitosamente

virsh detach-device ShadowFax kingston.xml
El dispositivo fue desmontado exitosamente

which means the device is succesfully attached but is never seen in the vm

The records in /var/log/messages:

Sep 30 21:34:57 Balrog libvirtd: 21:34:57.288: warning : qemudParsePCIDeviceStrs:1411 : Unexpected exit status '1', qemu probably failed

from /var/log/libvirt/qemu/vm.log

husb: open device 1.7
husb: config #1 need -1
husb: 3 interfaces claimed for configuration 1
husb: grabbed usb device 1.7

this one keeps repeating even after the device is detached that is today but yesterday showed only once or twice at each try and when detaching this came out:

Warning: tried to detach unattached usb device USB Host Device

Im using fedora 13 with:
libvirt-0.8.2-1.fc13.x86_64
libvirt-client-0.8.2-1.fc13.x86_64
qemu-system-x86-0.12.5-1.fc13.x86_64

Can someone help me please

Thanks
