I stopped sddm, udisks, udev: sudo systemctl stop sddm sudo systemctl stop udisks2.service sudo systemctl stop systemd-udevd.service sudo systemctl stop systemd-udevd-control.socket sudo systemctl stop systemd-udevd-kernel.socket
After connecting the floppy drive, it did not run (seemed not to be turned on). Then I used sudo systemctl start systemd-udevd-control.socket The same behaviour. I connected my smartphone to check if the USB port was powered - it was powered and the smartphone detected the USB connection. After "sudo systemctl start systemd-udevd-kernel.socket" and connecting the floppy drive, it started to run. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1456338 Title: USB floppy drive is running without floppy To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/udisks2/+bug/1456338/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
