DirectLink doesn't work with Windows7 / AMD Radeon R380

[fabiop]

With Windows 7 64bit and Amd Radeon R380, DirectLink doesn't work.
In Device Manager there aren't error but in the display doesn't show anything.
I try on two different PC with the same configuration with same result.

Drivers intalled:
radeon-crimson-15.11-with-dotnet45-win7-64bit.exe
DisplayLink_7.9M3.exe

Is DirectLink compatible with my configuration?

In attach zip file created with your tool "DisplayLink Support Tool 1.0.0.25.exe".

Thanks
