I could not get the hardware above to work with VirtualBox.
I also understand what you mean now
You were referring to pcipassthrough which I have just learned today.
Should I change from VirtualBox to anything else that might get my hardware to work? Should I tried something by the name Xen (Virtual Machine)? I heard it has different type of pcipassthrough also.
I also contacted the support team for my hardware. They said they do not have Linux driver for it.
Any hint is greatly appreciated.
