Lenovo LT1421 Shows Blank Screen on Mac

I think that I have the same problem as the other posters. I have a brand new MacBook Air 13" running OsX 10.8.4 and just purchased a USB3.0-DVI adapter from StarTech (USB32DVI). I installed the latest 2.0 drivers from DisplayLink but there is no sign of anything appearing on the screen or in System Preferences.
I've run the Disk Utility permissions fix and reinstalled the drivers.
I have confirmed the existence of the Displaylink files in /Library and also the existence of the daemon in ps:
new-host-4:LaunchAgents rlutwak$ ps
PID TTY TIME CMD
282 ttys000 0:00.02 -bash
new-host-4:LaunchAgents rlutwak$ ps ax | grep Display
75 ?? Ss 0:02.55 /Library/PrivilegedHelperTools/DisplayLink/DisplayLinkManager
230 ?? S 0:04.73 /Library/PrivilegedHelperTools/DisplayLink/DisplayLinkUserAgent
294 s000 S+ 0:00.00 grep Display

How do I know that my hardware isn't defective?
