Things to note: 1. Make sure that a driver (module) is not attaching to the device in the host OS, blacklist it if possible. 2. Only USB 1.1/1.0 devices are supported. If you have a pure USB 2.0 device, it is not going to work. You could try passing up the whole PCI USB device, but I have had little success.

Thanks Greg. Then my problem is with usb 2.0. Exists some roadmap from redhat/fedora about when will be implemented this option??
