The HDMI port drives a second monitor fine but the USB-C port will

Generally, you'll see that described in technical specifications as
"DisplayPort over USB-C" or "USB-C with DisplayPort". ASUS's site
describes that port as "Type-C USB 3.0 (USB 3.1 Gen 1)". I'm not saying
it doesn't support DisplayPort, but is there a reason that you think it
does?
As far as I can tell, the kernel logs you see just indicate that it's
detecting a USB hub in the monitor, not that the display itself is
supported.
