Xen users - Dec 2009 - USB Pass through to a Para Virtual Machine

Hi Folks;

I''m having a tough time getting my VM to "see" a USB device
connected to
my PC.

The HOST sees the device just fine:

[root@VE3RSD-TEST ~]# lsusb
Bus 002 Device 001: ID 0000:0000
Bus 005 Device 001: ID 0000:0000
Bus 005 Device 002: ID 10cf:5500 Velleman Components, Inc. 8055 
Experiment Interface Board (address=0)
Bus 004 Device 001: ID 0000:0000
Bus 001 Device 001: ID 0000:0000
Bus 003 Device 001: ID 0000:0000
[root@VE3RSD-TEST ~]#



I have the following in my xen config file for my VM:

usb=1
usbdevice=[ ''host:10cf:5500'' ]


However, when I do a lsusb from the VM, the device does not show up at all.


I''ve read some stuff on the web about passing the entire USB
controller,
where the controller is a PCI based card.  In my case, the USB 
controller is the on-board USB ports.  I do not have a spare slot to 
install a PCI card either.

Can anyone help? - this is critical to my VM rollout.

Thanks!

Ramesh.

<-- Hi Thave;  Tried that and no luck!  I have also unloaded the 
uhci_hcd module from the HOST O/S so that the host no longer
''sees'' the
USB device... I read on various websites / documents that the host 
should not see the device to prevent it from being used by the Guest.... 
   and still no joy!

Cheers,

Ramesh.
