Hi MarkM

Just me try and make things less frustrating. It sounds like the DisplayLink chip in this dock (DL-3900), which provides the audio Ethernet and video on this dock, is not being recognised on the USB bus.

V5.6 will not work with this dock, as v6.0 was the first release to support our DL-3xxx family. So let'ss try getting it working with v6.3 release.

As it sounds like the chip is not being detected on the bus, but you don't say if you are connecting to USB 2.0 or 3.0 ports. My first though is "Are you connecting it to a USB 3.0 port?". We know that early versions of host controller drivers have bugs that prevent it correctly recognising our USB 3.0 devices, which they have fixed in later releases.

Check out this article on our website to find the latest USB 3.0 drivers

If this is not the case, please can you post the system logs, with the dock connected, and 6.3 installed to see if that gives any further clues to the issue?

Thanks Wim. It works fine under Win7 whether I utilize USB 2.0 or 3.0. The issue I am currently dealing with is an HP 2560p under XP on USB 2.0. Although a Samsung Series 9 has the same issue.

I will probably have to wait till Monday to gather the logs.

Thanks for the assist.

Hi Wim,

I just wish this would behave the same way twice in a row. I re-imaged the laptop and installed v6.3M0. All the devices were detected but I could not get the external monitor to work on HDMI or DVI. I rebooted the PC. Everything except the USB hub disappeared.

This is an HP 2560p utilizing USB 2.0.

Hi Wim,

I just re-imaged the machine again and performed the exact same steps. This time only the USB hub was detected. This is sooo weird.

Hi MarkM

It looks like the DisplayLink chip is not being detected on the USB bus. I suspect this is a hardware fault with the dock.

Could you contact your Targus rep and see if they have a replacement unit for evaluation? Hopefully this should solve the issue and you can do a proper evaluation.
