So a few things: 1. Qubes has pcie hotplug disabled in the dom0 kernel, which TB uses for PCIe-based thunderbolt devices. This is disabled for security reasons. 2. The TB alternate mode that supports USBs might not instantiate the PCIe USB controller it connects through *until a USB device is connected to that port*. 3. Therefore...depending on BIOS support...you *might* be able to have a USB device seen by qubes if the USB device is plugged in at power-on. Even if that works, it might be on a USB PCIe controller that is not already attached to your sys-usb (if you have one). 4. If it does work, you might want to create a sys-usb-c which you run only after connecting a device to the port at boot time, and assign the (usually hidden) PCIe USB controller that that VM only.
