Created attachment 162461 [details] journalctrl kernal log My machine is Thinkpad Yoga with Onelink dock attached. Onelink dock is a USB 3.0 dock functioning as a USB 3.0 hub. This has two USB 3.0 ports in front. I connected a USB HDD enclosure to one of those ports. After use, I safely removed the storage device. But immediately that storage is connected. There is no such issue for laptop body's USB 3.0 ports or Onelink dock's USB 2.0 ports. I've tested in GNOME GUI and i3 CUI environment. In GNOME, I used gnome-disk utility. In i3, I echo'ed 1 to that USB 3.0 enclosure device's sysfs entry 'remove'. There is no difference.
