ASM1042A is a host controller, not a hub, but there is likely a hub between
ASM1042A and the USB ports on the monitor. 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.
