OK so that's an older Thunderbolt NVM. It wouldn't hurt to upgrade to the latest to see if it helps.
Unfortunately it's not yet on LVFS yet, but if you want to try to build it and flash it yourself here are the pieces you need: http://www.dell.com/support/home/us/en/04/drivers/driversdetails?driverId=3H3DP https://github.com/hughsie/fwupd/tree/master/contrib/firmware-packager Download the archive and those tools and follow the README.md in the link to the tools to build yourself a CAB with the update. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1745747 Title: No USB support for Dell XPS 13 9370 running Bionic 18.04 Status in linux package in Ubuntu: Confirmed Bug description: I recently received an XPS 13 9370. After taking a backup for 16.04 (in case this very thing happened), I installed the daily build of 18.04 as it didn't really make sense for me to hold on to a distro that'll be replaced in a couple of months. I noticed there were a few Dell repositories in sources.list, but non of them have bionic endpoints (only xenial). I copied those, in case they would be useful and went to erasing the disk and installing 18.04. Everything seems to work fine, except the USB / Thunderbolt ports. Nothing I try works, whether it be USB or Thunderbolt 3. If I look in dmesg, I can see the controller is recognising something, but it never lands in userspace: [ 1807.837379] xhci_hcd 0000:39:00.0: Host supports USB 3.1 Enhanced SuperSpeed [ 1807.837410] usb usb4: New USB device found, idVendor=1d6b, idProduct=0003 [ 1807.837412] usb usb4: New USB device strings: Mfr=3, Product=2, SerialNumber=1 [ 1807.837413] usb usb4: Product: xHCI Host Controller [ 1807.837414] usb usb4: Manufacturer: Linux 4.13.0-25-generic xhci-hcd [ 1807.837416] usb usb4: SerialNumber: 0000:39:00.0 [ 1807.837549] hub 4-0:1.0: USB hub found [ 1807.837558] hub 4-0:1.0: 2 ports detected --- ApportVersion: 2.20.8-0ubuntu6 Architecture: amd64 CurrentDesktop: ubuntu:GNOME DistroRelease: Ubuntu 18.04 InstallationDate: Installed on 2018-01-19 (10 days ago) InstallationMedia: Ubuntu 18.04 LTS "Bionic Beaver" - Alpha amd64 (20180118) Package: linux (not installed) Tags: bionic wayland-session Uname: Linux 4.15.0-041500-generic x86_64 UnreportableReason: The running kernel is not an Ubuntu kernel UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip libvirt lpadmin lxd plugdev sambashare sudo _MarkForUpload: True To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1745747/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
