DisplayLink Display Adapter issue on Win 8.1

[molo]

Hi,

I'm having issue with my USB 2 Display Adapter on Windows 8.1 (model WS-UG17D1)

I tried different drivers version, 7.4, 7.6, 7.7M4
and the one provided through Windows Update and they all do the same :

When I plug the adapter, the led switch on for about 1/4 of second before switching of and then, nothing...

The device is properly recognized under Windows devices management
I tried different USB ports on different controllers (USB 2 and 3)
I tried different USB cables
I tried to uninstall and reinstall properly each driver version
I even tried to format and reinstall Windows from scratch

And also tried the "DisplayLinc cleaner tool" before reinstalling last version (as described on the website)
and the "HOWTO: Debugging issues on Windows with DisplayLink"

Still the same issue.


The computer is a laptop (HP 8570p) and you can find the log from "DisplayLink Support Tool 1.0.0.22" attached.

Any help would be really appreciated.
Thanks
