XPS 13-9365, WD15, USB ports stopped working after update on 4/5/19

i have the same problem, which causes me to restart the computer... once i restart, i get the blue screen of death.

Thank you for your message. Does the keyboard & mouse work fine when connected to the system directly?

Have you tried using other ports on the dock to check if that works?

Disconnect all device from the dock & unplug the dock from the system. Connect all devices to the dock first & then connect the dock to the system & turn on the notebook & check if the issue persists.

How to locate the service tag

I'm having the same problem on my XPS 9365 with a WD15.  It was right around April 8 that I noticed this problem.. I had done nothing (no removal or addition of USB devices) in the days leading up.   I've had this setup running for the last two years since I purchased my laptop.  Prior to noticing this thread, I called Dell Support on April 15, 2019 and initiated Service Request:  .  The result of the service was to get another WD15.  I received and connected it today and have the same results i.e. no USB ports working, no USB audio.  However the HDMI port continues to work.

I'll call Dell Support tomorrow and pass this note along.  When I initiate another service request.  I'll let you know what I find out. P.S. I checked the BIOS for the Thunderbolt port settings and all external USB ports are enabled.

I have a similar issue. the USB ports are not working on the Dell Dock D3000 docking station.  They will power the device, but no connectivity.  Everything work fine until Windows did an update last week. I was on a support call with MS for a couple of hours troubleshooting to no avail.  In Device Manager, the is and error "Unknown USB Device (Device Descriptor Request Failed)"  I have uninstalled and reinstalled all the Displaylink SW and drivers and have made sure I the most recent updates including BIOS and Chipset.  I have tried a different Dell Laptop and it has the same issue.  Any help would be greatly appreciated!! Thank you!

VicDew,

Have you rolled back the Windows update that caused the issue?

Jesse,

Thank you for responding.  I did try rolling back and it didn't work either.  However, I was able to fix it after contacting Display Link directly.  Believe it or not after 4+ hour of trouble shooting, it was fixed by simply unplugging the power to the display port for 10 seconds and plugging it back in!!!

I had the same problem with the same laptop and WD15.  After two new WD15's with reinstalling drivers and sending my XPS laptop back to Dell to be repaired, the WD15 USB ports still did not function.  I was ready to send my laptop back on 5/10 for another go at fixing the laptop and Dell Updates occurred (I believe the updates occurred on 5/11).  I cannot remember what the update was,  but it had to do something with either the Thunderbolt firmware or the Thunderbolt controller.  Once that completed, the WD15 worked fine.  It would be interesting to know what was pushed around  5/11.

Hi! I am facing the same problem. My WD15 USB ports are not working after the Dell drivers update. I have tried disabling the selective USB suspend setting but it still didn't work.
