@Joseph, Hmm, OK. So you may already know this but USB and Thunderbolt devices are handled differently. I would treat these as two distinct separate issues.
Do you have any TBT devices that are not eGPU? It would be good to know if the problems are specific to eGPU. -- 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
