A lengthy Q&A on Unix & Linux addresses this issue:
After many pages of scrolling the solution is a new udev rule:
# enable in-kernel media-presence polling
ACTION=="add", SUBSYSTEM=="module", KERNEL=="block", ATTR{parameters/events_dfl_poll_msecs}=="0", ATTR{parameters/events_dfl_poll_msecs}="2000"
ACTION=="add", ATTR{removable}=="1", ATTR{events_poll_msecs}=="-1", ATTR{events_poll_msecs}="2000"
The Q&A is far too long to repost here, but please read the entire link to learn more.
