Have you tried to see what happen when using only th USB adapter?
Still have same problem?
Anyway I doubt you'll find enough power to handle twin head display.

Ciao

if you set displaylink screen default screen and hdmi screen as server (in xorg.conf), then you can run in default screen for browsing etc (after login) ... if you play ctrl alt f2 you can open the hdmi screen and without X you can run movie via mpv (and hardware acceleration) then ctrl alt f1 you get default screen running and movie running in server screen (without X). Running a movie (hdmi) and chromium(displaylink) is fine.
