hp usb 3.0 3005pr port replicator

hp usb 3.0 3005pr port replica
Microsoft Windows 7 (32-bit)



Why does hp usb 3.0 3005pr port replicator work with HP EliteBook 820 G3 Core i7 8GB 256GB SSD 12.5"`???


I plugged in the replicator to the laptop, started the laptop but get a black window saying Missing operating system.

I unplugged the replicator, re-started the laptop, no black window, I log in as always and everything is fine.

I plug in the replicator again, but the system doesn't recognize it.

When viewing the list of devices and what's connected to the laptop, it says "Unknown device connected" but updating the driver doesn't help.


I download the driver from but each time I restart the laptop I get the black window and "Missing operating system".


When I finally manage to update the driver of the replicator, I get the following message:

"Incompatible disply driver. The installed version of DisplyLink USB Graphics software does not support this graphics card, which uses a newer version of the Windows Display Driver Model. Please visit to check if a newer version is available."


When I visit the site and download the newer version, I get blue screen.


So, it seems to be impossible to install the replicator to this laptop.


I tested the replicator to another HP laptop from 2011 and it worked perfect!


What can I do to make it work???
