Could you explain why subsystem=USB does not make sense? I was simply following the documentation for USB devices (right above the section you linked to).

For what it's worth, I've also tried mounting the specific character device related to the appropriate android device into the container in the way you suggest, with no luck; `adb` still does not recognize the device.

Dear Fil,

I am not sure if my answer can help you.

I had ever asked a similar question to Daniel and I was using a thirty-party card. As a container uses a shared kernel with the host, so hostdev mode='subsystem' doesn’t make sense. Maybe you can try to use hostdev mode='capabilities’. Please see http://libvirt.org/formatdomain.html#elementsHostDevCaps

Hope this helps
