10 minutes work perfectly - connection loss afterwards

[Brummbaer]

Dear forum and product support,

I am already a fan of the DisplayLink idea - it's great as long as it works.
I am running a Anker USB 3.0 docking station (6 USB ports, Gigabit-Lan, HDMI/DVI, external 2A power supply) on a Asus Zenbook UX32VD (Intel HD4000+nVidea GT620)

The operating system is Windows 7 Prof.
All drivers are installed and updated to the latest versions as far as I know.
For sure USB and Displaylink are up to date.
I enabled all USB options in Bios and stopped USB energy saving methods in the energy options.


The docking station works fine, every function is fine (Audio,Ethernet,HDMI,USB) until a certain point. Usually its about 10 to 15 minutes of working with the station. I tried all USB sockets.

At this point the external monitor turns off, connected usb devices stop running and Windows says: unknown devices registered. I can unplug the USB connection and replug it - it's still "unknown devices". Only cutting off the stations' external power supply and rebooting windows helps to make it work again

Where is the problem hidden?


I read about wrong USB cables with - but I'm using the stock one.
Attached the analysis tool report and two screenshots of how it looks after the connection got lost.

Bios: Legacy USB Support: Enabled
XHCI Pre-Boot Mode: Enabled
