I don't think so. An USB Display is typically an USB Device with Display,
non-touch or touch, and connected via USB2 cable. The display has an usb2
type-b port and connects to usb2 or usb3 type-A port. The protocol to transport
the video signal is from company DisplayLink (now Synaptics, they bought them).
The driver in SLES15 is "udl".
