FWIW With a Dell XPS 9360 and Kubuntu 17.10, same issue on the latest kernel and many previous:
uname -a Linux mulhollandd-XPS-13-9360 4.16.2-041602-generic #201804121130 SMP Thu Apr 12 11:32:17 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux lsb _release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 17.10 Release: 17.10 Codename: artful I will test the solution mentioned by @s-breedveld of applying: "pci=nomsi iommu=soft" and report if this helps. In my case this is a bluetooth mouse which disappears after suspend. A dmesg output indicates: [ 3380.759427] xhci_hcd 0000:00:14.0: xHC is not running. [ 3380.774604] xhci_hcd 0000:00:14.0: xHCI host controller not responding, assume dead [ 3380.774627] xhci_hcd 0000:00:14.0: HC died; cleaning up [ 3380.775306] usb 2-1: USB disconnect, device number 2 [ 3381.059095] usb 1-1: USB disconnect, device number 2 [ 3381.059098] usb 1-1.2: USB disconnect, device number 4 [ 3381.059408] usb 1-3: USB disconnect, device number 3 [ 3381.059735] usb 1-5: USB disconnect, device number 5 A power-down is usually required to fix this, a reboot does bring the device back to life. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1413440 Title: USB stops working after a while (xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command) To manage notifications about this bug go to: https://bugs.launchpad.net/system76/+bug/1413440/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
