I cannot verify as of when this issue started. I did use the USB devices in question with 18.04.1 (prior to the upgrade to 18.10) and they did work fine. Currently I have no chance to test a newer kernel. Will do as soon as possible It happens with USB-Sticks and some USB3.0 hard disks.

No trace of insert events in the system log. The same series of USB sticks gets mounted on the same machine if booted with a live 18.04.1 image or a MacOS boot disk (thus eliminating the machines as source of problem). On other machines running Ubuntu Budgie or Apple MacOS all of the sticks get mounted without problems (thus eliminating the sticks as source of problem) This is reproducible on any machine that runs Ubuntu 18.10 with up to date patch levels (thus indicating it may be a Ubuntu 18.10 issue) I use SanDisk USB 3.0 sticks (same vendor and product IDs) ProblemType: Bug DistroRelease: Ubuntu 18.10 Package: linux-image-4.18.0-10-generic 4.18.0-10.11 ProcVersionSignature: Ubuntu 4.18.0-10.11-generic 4.18.12 Uname: Linux 4.18.0-10-generic x86_64 ApportVersion: 2.20.10-0ubuntu13 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: wolf 1873 F.... pulseaudio /dev/snd/controlC0: wolf 1873 F.... pulseaudio CurrentDesktop: ubuntu:GNOME Date: Sat Nov 10 16:47:57 2018 HibernationDevice: RESUME=UUID=539744c7-33c6-44da-a8b5-8bcf95f7845d InstallationDate: Installed on 2018-04-30 (194 days ago) InstallationMedia: Ubuntu 18.04 LTS "Bionic Beaver" - Release amd64 (20180426) Lsusb: Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 003: ID 05ac:0273 Apple, Inc.
