I suspect this could be due to the Fresco Host controller. Could you try updating the driver to the latest 3.5.46 version from here:

Does the same issue happen if they use the USB 2.0 ports?

Thanks

Thank you for the link.

The relevant file is.......
FLUSB3.0-3.5.46.0 (Signed by Fresco Logic.)

See my earlier post for my results.

Ok, after a little more testing I have found that it is more stable but still not what I would call rock solid. This is with my Targus DisplayLink based SuperSpeed 3.0 port replicator. Does anyone have the same problems to report with other devices?

So I'm running the latest USB drivers and the latest DisplayLink.

My behavior is that randomly my Dell XPS13 Ultrabook seemingly looses connection to the port replicator. It's not always display, sometimes just the NIC drops off but it's using a Displaylink driver too. All in all this has not been a smooth experience and I can't recommend this yet as a solution to our non-technical staff.

I'd love to equip our Administrators with Ultrabooks and DisplayLink port replicators but not until I can work these issues out.

I've had similar problems with my Dell XPS 14Z and Targus USB 3.0 SuperSpeed Dual Video Docking Station with Power. In the morning I will connect the power to my laptop and USB connection, power on, and I will have USB connectivity (keyboard, mouse, USB drive), but no video and no ethernet. I figured out a couple weeks ago to just unplug the dock power and re-plug then everything appears and works fine.

I finally got frustrated enough with having to do this every single day, so today I Googled the issue and found this thread. A couple weeks ago when the problem started I had uninstalled all of the DisplayLink software and drivers, then downloaded and reinstalled the latest DisplayLink 6.3m0 software, but that didn't help any. It was the same whether plugging into a USB 2 or 3 port. I also tried downloading the Fresco USB drivers posted earlier in the thread, but upon installing it said it couldn't find any Fresco USB controllers (my dock apparently has a Texas Instruments Root USB Hub).

Interestingly enough, even though I was running the 6.3m0 software (latest on DisplayLink download site), this morning I ran Windows Updates and there was a DisplayLink software update posted that was published in the past few days. I installed that, rebooted, and now things seem to be working fine (for now).

I hope this continues to work. I've been really happy with this dock/laptop combination so far aside from these few bugs.

I'm pretty sure this is a hardware issue, not a software issue. How else would re-powering the dock fix the issue? Targus really should be responding to this.

This seems to be getting worse. Now even unplugging/re-plugging the power on the dock doesn't fix it. I've completely uninstalled/re-installed the 6.3M0 software to no avail. Still no video or ethernet connectivity, only USB. This dock is turning out to be a glorified USB hub and I'm really frustrated with it.

Does anyone from DisplayLink read these forums?

If you have a TI Root Hub in your laptop, the Fresco drivers are not going to work. You need to update the TI drivers, which can be found here:

http://www.station-drivers.com/page/texas-ins.htm

And for anyone else wanting to update the USB 3.0 drivers in their laptop, the latest drivers are linked from this article in our knowledgebase.

I would have expected it to work when plugging into a USB 2.0 port. When you connect to a USB 2.0 port and have the issue, can you use device manager, and "View Devices By Connection" and drill down the USB bus to see how much of the dock has appeared on the bus? Is the root hub of the USB dock there or is it just the DisplayLink USB chip that is missing?

Wim - I updated to the latest Ti USB3 drivers, but I'm still experiencing the same problems. After the Ti USB3 update I now have an Unknown Device showing up under the Generic USB Hub section in Device Manager. However, the Texas Instruments USB Root Hub and XHCI Controller show up fine.

I've attached a couple Device Manager screenshots if that helps any. The first is normal view (devices by type) of USB, second is devices by connection. Under device by connection I don't see the Ti USB.

Thanks for your help.
