Ok so I've installed the Inateck Superspeed 4 Ports PCI-E to USB 3.0 Expansion Card.
Installation and setup are easy and it's working like a charm.
Rift and sensor have been immediatly detected by the installation software as soon as I plug them in that new USB device.
No sounds problems this time so I'm really happy ! Everything is working smoothly.
Only one weird thing. :#
When i'm going in oculus home into the parameters section if I look at the details of the hardware (where you have the serial number and firmware number of your rift, sensor etc ...)
My rift shows USB 2.0 where my sensor is showing USB 3.0 !
The weird thing is that both of them are plug into the Inateck expansion card ..
.
Anyway I've just played to IL2 with my rift and I didn't had any trouble in game. So I presume it's OK
edit : Looks like I'm not the only one :
