What have to be done to get the WL-HDD mount an USB stick or USB HDD connected to the ASUS? How to mount it?

(Oleg FW is on ASUS running)

And - the 1000$ question: How can this be managed dynamicly? (ASUS is on, than plug USB stick - AUTOmount - unplug USB stick, plug USB-HDD -> AUTOmount it ... )

1k thanks for any help
