I have been struggling for the last couple of days to figure out why my thunderbolt ports (on the left side of the XPS 13) stopped working on Ubuntu 18.04. The right side USB port works well and charging works on all the ports. Also, because I have a dual boot with Windows 10, I checked if I had the same issues and, indeed, the USB ports don't work on Windows. By USB ports not working I mean that neither ethernet, HDMI, external memory nor USB hub are recognized.

I don't know if it is a coincidence but it happened after I tried to find a way to transfer file to my android device. Following this post (Trying to install android-file-transfer Ubuntu 18.04 Bionic) I did the following

sudo add-apt-repository "deb http://ppa.launchpad.net/samoilov-lex/aftl-stable/ubuntu artful main"

sudo apt install android-file-transfer

sudo apt install libmtp-common mtp-tools libmtp-dev libmtp-runtime libmtp9

Here are the things I noticed so far

• Windows can crash when I plugin a device on the left side (but not always) with a blue screen and a forced reboot


• When it does not crash, Windows shows an error "device not recognized"


• Ubuntu does absolutely nothing when I plugin a device on the left side


• Wifi/bluetooth work fine on both Ubuntu and Windows

I've been trying to solve that non-working USB port issue for a while now and here are the steps I followed:

• I checked that the USB devices worked on other computers and they work fine


• I updated the BIOS through Windows


• I installed all the Windows updates


• I uninstalled and reinstalled all the USB-related drivers in Windows


• I disabled/re-enabled all the USB-related options in the BIOS as suggested in https://www.dell.com/community/Windows-8/XPS-13-9333-USB-Ports-Not-Recognizing-Any-Device/m-p/4565350#M9012
  


• I disabled the USB security option in the BIOS (Switching from "User security" to "No security") https://eischmann.wordpress.com/2017/06/29/thunderbolt-security-levels-and-linux-desktop/
  


• I ran all the BIOS and Windows diagnostics/troubleshooter and no errors were detected


• I installed all the latest Ubuntu packages and updated the Kernel


• I turned off the computed and waited a couple of hours (some people on this website thought that it could originate from an overheating)


• I disabled the WIFI/bluetooth that could apparently conflict with the USB ports in term of CPU usage (18.04: usb or other removable devices are not recognized after update)


• I tried to disable the USB power management because of some potential problems mentioned in an old post (2 usb ports stopped working)


• I uninstalled the android-file-transfer related packages and removed the repository


• 
  EDIT: I tried to check the USB ports using a live USB key but the same error occurs

I run out of ideas so if anyone has a solution please feel free to reply. Thank you a lot.

Here are some kernel errors. Notably the "Cannot enable. Maybe the USB cable is bad?" that happends any time I connect a USB device on one of the left USB port.

$ dmesg

You should try to boot on a USB key with a Linux distro.
The portable Linux distros come with a robust and comprehensive driver set.

If that does not work you probably got a hardware failure.
