[ovirt-users] Problem with USB redirection

Hello everybody, I have installed a little infrestructure with ovirt 3.5.0.1 and I have some Windows 7 VMs created and working well. From linux client, when I go to user portal and open a VM (all these VM have defined in console USB support as Native) and I plug a USB pen drive, the VM takes it and I can use it from my Windows 7 VM. But I have a problem with Windows 7 clients. When I try to redirect a USB from my Windows 7 client to my Windows 7 VM the remote-viewer gives the error "USB redirections support not compiled in". Any suggest or idea about what is my problem? Many thanks in advanced, Juanjo.
