Help: Lenovo T500 + DisplayLink

[jeremym]

Setup:

Lenovo T500 with "middle" (Advanced) docking station.

Docking station has both DVI and VGA outputs.

I bought the Displaylink adapter because the standard VGA
output is fuzzy. Hoping the Displaylink's digital out
to my second monitor would be crisper.

I am sure the drive is installed correctly;
the version appears to be: 5.2.21746.0

The device appears happy in Computer Manager
as "USB Display Adapters | DisplayLink Display Adapter (8060)"

I am using Windows 7 RTM.

Problem:

-I cannot get ANY output on my T500 to the display link adapter.
-There is no GUI for the Displaylink on my computer to switch
-Win P does not show the Displaylink as a source to extend to
-At no time does the light on the displaylink ever come on.

What I've tried:

-Four different USB ports (two on the doc, two on the laptop itself)
-Uninstalling and re-installing driver. Using the Windows downloaded driver. Open to others.
-Changing from switchable graphics in T500 bios to DISCRETE
-Changing from switchable graphics in T500 bios to Integrated (losing DVI on the docking station; which is very important.)
-Changing back to switchable graphics
-Manually clicking on "DisplayLinkUserAgent"
-Manually clicking on "DisplayLinkUI"

Now, I'm stumped. No GUI. No light. Nothing.

Looking for help. Thanks.
