Trouble passing USB3 flash drive to a windows 7 vm

[derp]

Hi,

I tried passing an USB3 drive but to no avail, the device is stuck in "other device" with Universal Serial Bus (USB) Controller name and a warning sign in the device manager, whereas i have no trouble passing USB2 drives.
i tried different methods:
- using the vm conf file and adding either sb2: host=0951:168e,usb3=yes, sb2: host=0951:168e,usb3=1, or sb2: host=5-2,usb3=yes
- qm monitor with
device_add nec-usb-xhci,id=xhci,addr=0x1B,bus=pci.1
device_add usb-host,bus=xhci.0,vendorid=0x0951,productid=0x168e,id=anotherid

Do i need to update my vm drivers ?
Thanks

So I tried multiple ports with the usb3=yes setting and nothing worked, now without this usb3 setting I'm able to see my flash drive through my only USB2 port, all other USB3 ports don't detect it.
Also the speed is terrible, i only get 6MB/s.
