DisplayLink?

G'day, folks,
I'm wondering whether the 2015 reports of FreeBSD [1] supporting DisplayLink are still true, or overcome by events, or by technology advances, or other.
In short, I just have tried a Lenovo ThinkPad USB 3.0 Ultra Dock (ASM PN SD20K40266, FRU PN 03X7131, type 40A8). It hooks up to a USB SS port and several of its (and connected) devices are detected [3], [5] but the DisplayLink apparently does not get an extra driver attached [1].
udl(4) is loaded (which autoloads videomode.ko).
Xorg [2] sees the devices (which act as I expected [4]) but apparently has no concept of the DisplayLink device sneaking in via USB.
I had hoped for more mileage. What am I doing wrong?
Thanks for any indications, and
All the best,
Peter.
PS. If you think that freebsd-usb was a more appropriate place to ask, I'm happy to forward/follow up there.
