Wouldn't udev be the thing for this? When new h/w gets added it removed, udev will inform you via events. You can then do whatever you want in resp to it, eg send a msg over dbus to your specific service informing it of the event. Look at how std Linux distros handle such scenarios using udev. -mandeep <div class="gmail_quote">On Mar 22, 2013 7:54 PM, "Keyur" <<a href="mailto:keyur.patel@einfochips.com">keyur.patel@einfochips.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> Hi, My requirement is to monitor Ethernet and other peripherals on my board.
