[CentOS-virt] Pass iPhone/iTouch through kvm to Win7 VM?

Started this over on the main list, but remembered there is a
CentOS-virt list also where this would be more appropriate.

At home, I'm all Linux and only run Windows in VMs when I absolutely
have to (e.g., TurboTax on Win7 during the tax filing season). 

Now I'm trying to get Win7 running in a VM on CentOS
5.6 and kvm to connect to my iTouch and iPhone so I can sync them with

When I plug the iPhone in and run lsusb I get an address of 05AC:12A0

Bus 006 Device 001: ID 0000:0000  
Bus 007 Device 001: ID 0000:0000  
Bus 005 Device 001: ID 0000:0000  
Bus 002 Device 001: ID 0000:0000  
Bus 001 Device 011: ID 05ac:12a0 Apple, Inc. 
Bus 001 Device 001: ID 0000:0000  
Bus 004 Device 001: ID 0000:0000  
Bus 003 Device 001: ID 0000:0000  

I put that into a hostdev block in the xml file that defines the VM.

<hostdev mode='subsystem' type='usb' managed='no'>
        <vendor id='0x05AC'/>
        <product id='0x12A0'/>

But...no joy. Win7 works in all other aspects...just won't connect to a
usb device.

Anyone get kvm to pass an iTouch or iPhone through to the VM so it can
communicate with iTunes?

I'm thinking this may be a permissions and SELinux issue...the usb
device is owned by 'dave' (my CentOS login id), but the VM is owned by
kvm (different owner and different SELinux context).

I remember reading a lengthy discussion on how to get kvm to run as as a
regular user...will have to go find it.

Once I clean the host up and back up some data, I'll be migrating to
CentOS 6.2.  Does that version have more capability to deal with usb
