check by yourself the logs showing that my passed through devices are w= orking great :

But I have used a raw image file (not a physical installation on a sata or nvme disk,because in this case it=20 wont work and for this I've opened another bug). With this I want to=20 demonstrate that there aren't any problems with my bios settings and=20 with my passed thru devices.

=C2=A0My host graphic card is not an Nvidia card. It's the graphic chipset=20 integrated on the motherboard (CoffeeLake-S GT2 [UHD Graphics 630); to=20 use it I've installed the xf86-video-intel driver with this xorg.conf= =20 file :

so,now,let's to strai= ght to this problem :

I've created a new VM with the goal to passthru my graphic card and my usb=20 controller from the host os (freebsd 14-CURRENT) to the guest os=20 (freebsd 13R p7) and I've used the parameters below :
