Bug Description

I'm trying to passthrough USB Flash drive from Host to Guest with virt-manager with no success.

1. I'm starting virt-manager.
2. Putting my USB Flash drive into USB port.
3. Adding USB Host Device with my USB Flash drive. It appears in hardware list as USB 090c:1000 device.
4. I'm starting my VM and when it is finished no usb device I can see in my guest: lsusb doesn't shows it.
-------------------
I tried another way. When VM is started I executed:

$ sudo virt-xml Kubuntu-16.04.x-x86_64-14GiB --update --add-device --host-device 090c:1000
Для пристрою успішно виконано дію hotplug.
Домен «Kubuntu-16.04.x-x86_64-14GiB» успішно визначено.

But nothing's changed in guest system: no any new device appeared.
-------------------
I tried also:
1. Creating usbhostdev.xml file with the following content:

<hostdev mode='subsystem' type='usb'>
        <source>
                <vendor id='0x090c'/>
                <product id='0x1000'/>
        </source>
</hostdev>

2. $ sudo virsh attach-device Kubuntu-16.04.x-x86_64-14GiB /tmp/usbhostdev.xml

This also added USB 090c:1000 device in virt-manager but nothing's changed is guest system again.

I think this is a bug or something I'm doing wrong possibly.

Also I've tried 'virt-manager --debug' and adding USB Host Device. It seems output shows all is correct (http://pastebin.ubuntu.com/19548401/):

Greetings!
I take ~jacob/+archive/ubuntu/virtualisationrepository in Ubuntu 16.04.
The problem with usb passthrought.
Through virt-manager add a usb mouse/keyboard, run the virtual machine, and the vm does not see them.
Then I pull them out of the USB port, re-insert through virt-manager add a usb mouse/keyboard, and now vm sees them.
After turning off the vm, repeated all over again.
I do not know to whom to address this problem.
Thank you.
