One thing I noticed in common is our laptop detected the new monitor as:

Code:
: new high-speed USB device number 10 using xhci_hcd
: New USB device found, idVendor=0bda, idProduct=5412, bcdDevice= 1.27
: New USB device strings: Mfr=1, Product=2, SerialNumber=0
: Product: 2-Port USB 2.1 Hub
: Manufacturer: Generic
: USB hub found
: 2 ports detected
: new full-speed USB device number 11 using xhci_hcd
: not running at top speed; connect to a high speed hub
: New USB device found, idVendor=0bda, idProduct=5450, bcdDevice= 0.06
: New USB device strings: Mfr=17, Product=18, SerialNumber=19
: Product: BillBoard Device
: Manufacturer: Realtek
This is puzzling. Based on the documentation it seems that the monitor's USB vendor ID should be 17e9

Code:

I have tried the github manner, as well as installing the vanilla displaylink-driver-5.4.1-55.174.run. same observation.

Would greatly appreciate any advice / idea / pointer. Thank you.

PS: forgot to mention, the vanilla displaylink driver and the same Asus monitor works on a Dell laptop, fresh Ubuntu 20.04 installation. lsusb shows correct vendor ID on that Dell laptop
