Denon Prime 4 - Ableton Link via USB or only via LAN?

Hi, I have a Prime 4 and a Wolfmix W1. The Wolfmix can be synchronized to music via Ableton Link, but it only has USB connections. Does the Prime 4 also output the Ableton Link signal via the USB ports? So far I have not been able to synchronize the Wolfmix with the Prime 4 via Ableton Link. Thanks in advance.
