Display adapter is not working - Win 8

[NdV]

Hello,

I have problem with Kensigton dock station display adapter. For like two weeks adapter is just not working. I've tried to reinstall multiple times with different drivers version, but unfortunately without any positive results.

I've notice one strange thing thou - when device is connected to older USB port - I can see DisplayLink software icon in tray (obv only laptop display is working).

Do you maybe know what I should try in order to make this working?
