Hi,

Sorry if this sounds like a newbie question, but the search on the archives 
kind of suck.

I just finished (successfully after much pain) get hotplug to initialize a 
device for me when it was plugged in.  But to do this I had to bypass all of 
the existing net.agent script.

I am guessing I didn't find the right documentation.  I will tell you what I 
did and hopefully someone can tell me what I should have done.

Have usbnet loaded as a module.

in /etc/hotplug/net.agent  before anything, do 


mesg Checking for subscript for $INTERFACE $ACTION
if [ -x "/etc/hotplug/interfaces/$INTERFACE" ] ; then
    mesg Calling subscript for $INTERFACE $ACTION
    /etc/hotplug/interfaces/$INTERFACE $ACTION
    exit 0
fi

and in /etc/hotplug/interfaces reacted to the arguments registered and 
derigistered to do what I needed for /dev/usb0

Ideally I would always like to say... for devX put file into interfaces/devX 
and in that file do X for plugged in and Y for unplugged.  Just like the 
init.d scripts.

Information on why my approach is wrong would help, the page 
http://linux-hotplug.sourceforge.net/
talked a lot about what hotplug without ever getting to the one question most 
people would have...
"I have new device X and I want Y to happen when I plug it in.  What do I do?"

Thanks for any information.  If it turns out this description isn't in 
existence yet (for users who just want an answer to the above question, not 
understand how hotplug works) then I might do one up.

Ian.
