I don’t have a direct solution to your problem, but in case you can’t resolved it, what you can do it is to combine sys-net and sys-usb so that sys-net has access to the USB controller and fulfills
the function of sys-usb.
But it will cost a bit of your security doing that
What Qubes OS version are you using ?
What is the version of your kernel ?
What is the model of your NIC card ?
