With three USB-A ports on there, it is a shame it can't do that.
I had a crazy idea, and I think it works: Use the Zen to convert the XAC into something the Quadstick can read on the USB-A port. The Quadstick can use the inputs from a Dualshock 4 controller and the Zen can emulate one....
So I clicked on Enable PS4 Speciality (For PS5 Console) and set the Emulator Output Protocol to Playstation 4/5, then plugged an XBox controller into one of the ports on the front of the Zen and voila! It worked.
XAC -> Zen -> QS-USB-A -> QS -> PC -> QMP 4 -> virtual XBox controller for PC games.... ?? PROFIT!
Next, run QMP 4 and enable the virtual XBox controller emulation....
I also had the PROG port on the side connected to the PC for some extra power for the Zen/XAC part and for monitoring it with ZenStudio.
This could be useful for a lot of random controllers that people might want to use.
