Comment 7 for bug 1552241

Hmm, I had the same issue passing an USB dongle.

But today saw same system, same USB port but other device works fine.
$ cat cellphone.xml
<hostdev mode='subsystem' type='usb'>
    <source>
        <vendor id='0x22b8'/>
        <product id='0x2e82'/>
    </source>
</hostdev>

Generated correctly
   "/dev/bus/usb/002/018" rw

So when getting to develop something to upstream for virt-aa-helper in that regard I need to make sure I find the difference between the two.
