Constant disconnects with Dell XPS 15 laptop and Plugable USB-C Triple Display Docking Station

After reading the Plugable FAQ to check for compatibility, I just bought a brand new Dell XPS 15 (6560) laptop and a Plugable USB-C Triple Display Docking Station, but I’m having the issue with constant disconnects making the dock completely unusable. I’ve searched the web for a resolution and have tried all the recommendations I could find, e.g. I’ve installed the Plugable DisplayLink drivers, I’ve updated to all the latest drivers and BIOS from the Dell website (including Thunderbolt & Graphics), I’ve tried switching to Wi-Fi Airplane Mode, I’ve tried closing the laptop lid, etc., but nothing works. It just keeps constantly disconnecting and reconnecting every couple of seconds. My monitors are 2 Lenovo ThinkVision LEN L201p 1600x1200 monitors with brand new Cable Matters DVI-D -> HDMI six foot video cables. The dock is connected to the laptop through the USB-C to Thunderbolt 3 port. I am desperate to get this working, so I hope Plugable can find a resolution. Thanks, Craig

Have you tried connecting the original laptop power supply? I had the same problem with the same model laptop, 9550 in my case. When I connected the power supply, the disconnects stop. I am not saying this is a solution, but it may be a work-around.

Hi Craig,

For the benefit anyone else following this thread, sending a one of our PlugDebug files ( to allows us to examine details about your system to help us determine the next steps.

If you have a Thunderbolt 3 system as Craig does, including a screen shot ( of the Thunderbolt 3 ‘Details’ information from your system by following the steps under the “How do I check which version of Thunderbolt 3 software and NVM firmware I am running in Windows?” from this link ->… is also very helpful.

Thank you,
