Thank you very much Michal, If I have checked Device administrator in my Windows 7 VM and as you can see in the attached image, the USB device is correctly installed. But when I click "File" in remote-viewer "USB device selection" appears in grey and I can't select any USB device.

Is there any other requirement to be able redirect USB devices?, Is it necessary to install usbclerk in Windows clients to redirect USB to the Windows guest?

Many thanks in advanced,

Juanjo.

Also I have observed something wrong in my administration portal. The oVirt documentation says that I have to select Native USB mode in console properties in VM configuration

yes, that's the only supported way
you should see the USB controller in devices

there used to be such issue in 3.4..it is fixed in 3.5 already.
It should be a UI problem only…

Thanks,
