I have succesfully achieved this functionality by adding PCIe USB controllers and using PCIe passthrough to isolate them to specific domain VMs. With USB extension cables it is as simple to use as if VMs were separate physical hosts, no problems whatsoever detected. USB controllers were produced by Unitek brand, generic chinese brand, PCie x1 card and 3.5 external bay USB front panel. All guests detected the devices without any problem.
And as for GPU, I chose to use a separate machine and utilize VNC and Nvidia Gamestream to game on Qubes Box, using one of the VMs as a Gamestream client. It required minimal troubleshooting due to the usage of unofficial Moonlight app for the client. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
