Re: Dell XPS 13 9380 Thunderbolt 3 (USB Type-C) stopped work

Jump to solution

Confirmed, installing BIOS version 1.3.2 (25 Apr 2019) resolved the issue.

Fixes:
- Fixed an issue with Secure Boot Option ROM Signature Verification.
- Firmware updates to address security advisory INTEL-SA-00185 (CVE-2018-12188 CVE-2018-12190 CVE-2018-12191 CVE-2018-12192 CVE-2018-12199 CVE-2018-12198 CVE-2018-12200 CVE-2018-12187 CVE-2018-12196 CVE-2018-12185).
- Firmware updates to address security advisories INTEL-SA-00191(CVE-2018-12201, CVE-2018- 12202, CVE-2018-12203, CVE-2018-12205).

Enhancements:
- Removed the option Always Allow Dell Docks from BIOS settings. Dell dock connection and the port behavior will be controlled via the USB and Thunderbolt Adapter configuration settings under operating system environment.
- Replaces Absolute Software service from Computrace to Absolute Persistence Module service.

Okay, so this worked for me... it's a variation on what some others have said. With all devices and power unplugged from the USB-C/Thunderbolt ports (nothing can be using them), fully power down the laptop, then start it again. To be clear, this will not fix the issue in the long term. I saw the problem reappear twice now since my initial post, but that procedure has also temporarily resolved it each time.

Been having the issue disappearing and reappearing every now and then.

 

There's been a new firmware released which sounds like it should resolve it!

Specifically

  • Removed the option Always Allow Dell Docks from BIOS settings. Dell dock connection and the port behavior will be controlled via the USB and Thunderbolt Adapter configuration settings under operating system environment.

 

fwupdmgr refresh
fwupdmgr update

To install it right away.

Hello, 

I have similar issues with my new laptop XPS9380 on linux Ubuntu 18.04.
The "classic" USB-C on the right side of the laptop works correctly in all conditions (mouse, keyboard, external hdd, dock...)
The two Thunderbolt 3 on the left side does not work for external hdd, docks, etc... but it works for mouse and are correctly powered (external hdd physically "turns" but are not seen by the OS).
Another interesting point, if I connect dock and/or external hdd on the laptop BEFORE switching on the computer, they are correctly recognized by the OS (and then i can use all the features of the dock, USB, display, ethernet...). So it seems that thunderbolt port are "desactived" at the start if they are not connected. 

I already updated the firmare/BIOS to the last version 1.3.2 and I tried with no success :
- activate/desactivate the C-state option
- the two mode of thunderbolt (BIOS-assist and native). 
- set thunderbolt security mode to -> no security

If anyone has an idea 🙂 ,

Thanks

For what it's worth, I am experiencing this same kind of issue with a new XPS 13 9380 with Ubuntu 19.04 installed. The machine already has the latest system firmware (now 1.4.0, or 0.1.4.0 as fwupdmgr calls it) installed, so it's not an issue that has been solved by firmware thus far. In my case, one thunderbolt port suddenly stopped working after a couple of weeks -- it still charges the computer and connects to single USB devices, but won't work at all with my USB/HDMI hub. The other two ports are still fine with the hub. Powering down the computer didn't seem to help, but I haven't yet dug into some of the other workarounds presented here (e.g. running system diagnostics).

I'm facing a similar problem after automatic update to BIOS 1.4.0 running Ubuntu 18.04. Connecting Mice, Flash-drives or external USB HD works, but the USB-C Hub does not anymore. The Hub still works on the 1st USB-C slot on the left side though.

I've contacted Dell support and hopefully get a solution soon.

To follow up, I shut my computer down for a few hours and when I turned it back on all my ports were working fine again. So it seems the problem is intermittent. Hopefully there will be a firmware update or something that addresses it, but at least it's only a temporary nuisance in the meantime.

Yes, you have to fully shut down the computer, not just restart.

My feeling is that all other approaches mentioned in this thread work only because they include some form of shutting down and starting again the computer.

Hi, I upgraded to 1.5.0 and the issue was still there. Then it even got worse and my port 1 did not work at all. I had the machine shut down and ran the ePSA diagnose. No error was detected by this program. Finally I shutdown the machine for several hours and wow, the ports are working again - very strange. Hopefully it is not a heating problem and this stays for a while and get fixed soon in a upcoming update. Keeping fingers crossed 🙂
