Seldom Displaylink disconnect
 

Greetings. We have several laptops with same problem - HP USB Graphics adapter sometimes disconnects. It happens relatively seldom, after screen "blink" there is a message that USB-device is connected. Tool log after last issue attached. USB drivers reinstalled, different ports and adapters tried.

Hello Stanislav,
thank you for contacting us.

I can see some errors in the logs but it seems that you haven't set Advanced Logging. Can you do it as described here: http://support.displaylink.com/knowl...rticles/533818
and provide those logs?

BR,

Hi,

The logs confirm that there are USB connection errors.

Do you still get these issues if you swap USB cables?

I see you have tried most things I would have suggested - please review this FAQ for some further suggestions: http://support.displaylink.com/knowl...from-repeatedl

Hello,

Different adapters been tested on different builds of software, on all ports. Latest USB drivers have been installed. I am aware that problem affects 3 laptops, while other laptop from same series work without this issue. I made advanced logs, but i can't reproduce problem manually, so it might be long time since last disconnect occur.
