dell xps + windows 8.1 prof - no USB devices after upgrade

[brybak]

Hi,

I had a dock D3000 with Windows 8.0, it worked (with problems, but worked) till I've upgraded to 8.1 (without upgrading Displaylink). It stopped to work at all.
Then I did uninstall of Displaylink, cleaning, installed 7.5, rebooted many times. After plugin the cable, computer seems to see "something" as it creates buzz after plugin/plugoff, but nothing is visible in device manager. Dock is powered, ethernet is blinking.
In C:\Windows\System32\Drivers I can't see any displaylink drivers. Please see my log attached.

I'd appreciate for your help.
