As a workaround you could edit /usr/share/hal/fdi/information/10freedesktop/10-usb-music-players.fdi and remove the whole section dealing with the "<!-- Feiya Technology Corp Memory Bar -->" device from "match key" to "/match". This would prevent it from showing up with the iPod icon and prevent rhythmbox from launching.
