Maybe the same hub which shows up when the monitor is plugged into USB instead of Thunderbolt. Could you post "lsusb -tv" for both connection variants with the same mouse= in the same monitor port? Maybe see if dynamic debug spits out something useful: echo 'module xhci_hcd +p' >/proc/dynamic_debug/control dmesg -W >log.txt Then connect the mouse with your udev rule, make a few clicks, disconnect, remove the udev rule, connect again, make a few clicks. Attach the resulting log. --=20 You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.=
