The solution works fine. The tracking/performance is just perfect. except that unfortunately it fails if both 0bb4:2c87 is added, the VM will crash, which means the integreated camera can't be used...
The only solution for that is passing through a whole PCI USB controller...
The integreated camera can now be used.
