UR44C connect to computer DAW and iPhone

Hi,
Is it possible to have your UR44C connected to computer with DAW (Cubase) and send the audio out to an iPhone at the same time?
For example: I have my guitar plugged to input1 and a plugin effect in Cubase on the computer (Windows 10). I’m playing to a backing track in Cubase and I want to send out the final mix to my Iphone.
I’ve heard that the Steinberg interface does not work with USB hubs. Is it possible to use the loopback function some how?
