Default DisplayLink (ASUS MB16AH) USB-C device not recognised

A brand-new ASUS ZenScreen MB16AH bought as a replacement for an older USB screen does not want to connect via USB-C.

All the s/w is at its latest for the time of writing:

* OS: Ubuntu 22.04
* Kernel: 5.15.0-40-generic
* EVDI kernel: 1.11.0 of
* DisplayLink: 5.6.0-59.176

The screen works via HDMI, but shows no signal if connected via USB-C. The spec for my laptop says that all USB ports are USB 3.1. An older version of ASUS MB169B+ works just fine.

Running `journalctl -b` after connecting the monitor returns this log:

Jun 24 11:17:59 mx-zen kernel: usb 1-2: new full-speed USB device number 70 using xhci_hcd

Jun 24 11:18:01 mx-zen kernel: usb 1-2: new full-speed USB device number 73 using xhci_hcd

and on it goes trying forever.

The monitor is definitely powered on as it displays the _no signal_ message and goes to sleep (amber light).
