A little update:
I found out that I have to activate *Hostdev Passthrough* (is this really
necessary for USB devices?). Now I see all the devices and I can add also
an USB device.
But I'm still not able to disconnect the USB from the old VM.

Subject: Can't add/remove usb device to VM
To: users <users(a)ovirt.org>
I run oVirt 4.2.1, in 4.1 I added a USB device to a VM and now I wanted to
change this device to a different VM.
But I found out, that I'm not able to remove this device nor I'm able to
add any device to any VM. The device list is empty.
I found a bug report, what describe this error:
Is there a solution for that?
The USB device is a hardware dongle and it is very impotent for us to
Any workaround is welcome!
