it is not possible with pure java. but you can use a native lib available on all important platforms, e.g. SIGAR lib from hyperic hq

This depends very much on the plattform your programm is running on.

in linux you can use the dbus api to register hardware changes

if you are only interestet in usb devices you should have a look at jusb (afaik there is even a windows port)
