Targus ACP70EU only detects Displaylink with HDMI connected
 

A couple of days ago i bought a new Targus ACP70EU USB 3.0 dual video docking station with DisplayLink controller. I use it for a music computer.

I connect the (touch)screen to the DVI port, but i don't use the HDMI port.

Windows detects the USB 2.0 and 3.0 HUB, but not the DisplayLink controller.

When i shut down my PC and remove the AC/DC power adapter from the dock, connect the HDMI port (to my TV), connect the power adapter again and reboot the laptop windows detects the displaylink controller and everything works fine. I also can disconnect the HDMI cable. When i do not disconnect the power to the docking station it works fine, even after several boots from windows.

But when i disconnect the power to the dock for a couple of minutes the whole problem is back again. And this is very unusable for a portable music computer. Can anybody help me? Thank you!

What is the ACP70 Item Number?
 

This is similar to a problem seen with some older ACP70, but not quite the same. I am curious however if maybe an older unit made it into new suppliers stock. What is the Item number shown by the model number on the bottom of the dock?

Hello Targuslevel3,

The item number on the bottem is 51. What does this mean?
I allready contacted Targus support yesterday evening and the send a response today with a couple of questions. Thats nice!
