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 :eek:

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

Maybe a hint?

Can someone help out? Is my description correct?

I think you have a HW problem. The SW logs actually don't show any detection of our hardware, but one of the systems descriptions shows that it had seen our device. If you ever got any life out of the HW then these logs don't show it!

Ill test on other computers and try to get a 'useful' failure report.
