how to get a more stable version of the qemu driver for the usb 3 contro

Hello to everyone.

I'm trying to connect two kinects 2 to a two different qemu-kvm virtual machines. On the first one VM I have passed the IGD video card from ubuntu to windows 10,following this tutorial :

and on the second vm I have passed the geforce RTX 2080 ti. The result is that the kinect 2 that's attached to the vm where I have passed the RTX 2080 it has a stable connection. While,the kinect 2 attached to the vm where I have passed the IGD gets disconnected as soon as I run the kinect verifier. I read somewhere that the problem could be the qemu driver for the USB 3 controller,because it is bugged.

This is the qemu version that I'm using :

root@ziomario-z390aoruspro:/etc/xen# /usr/bin/qemu-system-x86_64 --version QEMU emulator

I would like to know if I will get a more stable driver of the usb 3 controller if I make the upgrade of qemu and or kvm or what ever else. thanks.
