You can disable polling (which is better and more permanent than the "killall hald-addon-storage"), for example like this for any device with "Generic Flash HS" in its UDI:
lshal | grep '^udi.*Generic_Flash_HS' | cut -f3 -d" " | xargs -i+ hal-disable-polling --udi +
In my case, it was a card reader in the monitor that I don't use anyway.
