It does? Haven't looked at it. :)
Mine says USB\VID_17E9&PID_0360&REV_0112 USB\Class_FF&SubClass_00&Prot_00

I haven't tested it on Haiku but I will paste a list :)
Some more links :), right now I just collect what information I can get my hands on :)
http://www.openbsd.org/cgi-bin/cvsweb/~checkout~/src/sys/dev/usb/udl.h?rev=1.21;content-type=text%2Fplain;only_with_tag=HEAD http://www.openbsd.org/cgi-bin/cvsweb/~checkout~/src/sys/dev/usb/udl.c?rev=1.76;content-type=text%2Fplain;only_with_tag=HEAD http://floe.butterbrot.org/displaylink/doku.php
What would be the best approach? Borrow udl.h from openbsd but make our own usb_grafic.cpp based on usb_audio?

As this is vendor-specific device the name usb_udl is preferred. In my opinion, the name usb_graphics should be reserved for devices of standard USB Monitor Class. Looks like the device works using bulk transfers so usb_audio cannot help a lot implementing the usb_udl driver.

Getting this with listusb -v

Here's the listusb -v from a mimo UM710S usb touch monitor, in case it is off any help:

I removed the relation with UVC and isochronous streams as these devices use a vendor specific bulk-only interface.
