Dell XPS 13 and TB16 dock usb issues

There was a buggy USB driver (see https://www.dell.com/community/XPS/BSOD-Driver-Verifier-DMA-Violation-with-TB16-Docks/m-p/7250845/highlight/true#M25485), it looks like it was updated yesterday (4/22), maybe worth trying that update?

Driver did not fix the issue.  I have abandoned all USB connections to this dock at this time.  Looking for a solution for a video solution that will support 2-27's and 1-24 monitors as well.

This has gotten out of hand.

Thank you for your message. Is the system used with Windows or Ubuntu OS?

Do you connect the docking station after the system has booted or is it booted with the docking station connected?

Have you tried restarting the system when the USB ports stop working instead of reconnecting the devices?

Does the keyboard & touchpad on the system work fine when docked?

How to locate the service tag

I have the same setup 9380 + TB16 and I was with tech support for over an hour and even they couldn't figure it out. Their answer, return the TB16 and get another dock. It seems like the ASMedia driver is causing issues and Dell still hasn't figured out how to fix this. 

In my situation, the screens work and charges my laptop except none of the USB ports or ethernet port work. Supplies power, just doesn't recognize or send data 

@Jon YThe ASMedia driver shows updated today, 4/27, for my 9365.  What version do you show now?

You have done the TB 16 firmware update to 1.0.2?

I'm using windows, and i've tried all combinations with the docking station already connected or connected after booting up the system. The keyboard and touchpad on the system work fine when docked.

What is the BIOS version installed? Is it 1.2.1 or 1.3.2?

Please update the TB 16 firmware to version 1.0.6 from this link

Did you update the ASMedia drivers as @Saltgrass suggested?

If the issue persists, please share the service tag & registered name. I will have this escalated.

The TB16 Bios is 1.3.2

The ASmedia drivers are the latest 1.16.56.1

I'm having the same issue, tried everything I could find to get it working properly but can't stop the USB ports from cutting out after a few minutes.

Latest dock and XPS firmware.

I'm seeing this too on a brand new XPS 13 9380 with system firmware 1.3.2 and the TB16. I'm on Fedora rather than Windows so it looks to be a cross-platform issue. I've resorted to using the usb C-to-A adapter that came with the system plugged directly into the laptop.

I realize this isn't an especially convenient fix for anyone, except perhaps those who are still within their return period, but Dell just launched their new WD19 family of docks.  The Thunderbolt version is the WD19TB.  Among the changes that might be of interest to users in this thread:

- Its driver page lacks an ASMedia USB controller driver.  That might be an early launch glitch, or it could be that the WD19 family has dispensed with that controller and might therefore avoid USB issues encountered on the TB16.

- It specifically highlights Linux functionality, including the ability to update the dock firmware on Linux, which I don't think is possible on the TB16.

- The Thunderbolt version is actually backward compatible with regular USB-C systems, which the TB16 is not.  I expect Intel's new "Titan Ridge" Thunderbolt controller chip is responsible for that capability.

- It supports systems that provide DisplayPort 1.4/HBR3 through their USB-C/TB3 ports, which will enable higher-end display setups, especially for USB-C systems.  Thunderbolt 3 systems don't see quite as much of a benefit here because they start bumping up against bandwidth limitations of Thunderbolt 3 itself, but even they get boosted to dual 4K 60 Hz + single QHD compared to dual 4K 60 Hz on the TB16.  That said, systems with DP 1.4/HBR3 over USB-C/TB3 are still rare today, although that will change once Intel's "Ice Lake" CPU platform rolls out, which is slated to begin at the end of this year.

I've tried the dell TB19 dock and have the same issues.

Dell won't even let me return the item

horrible customer service and support
