How to automatically start or stop Bluetooth service when USB bluetooth dongle inserted or removed?

[Alex Cruise <alex@xxxxxxxxxxxxx>]

Hi there,

I have a cheap little USB Bluetooth dongle which works great, 
unfortunately I only have one, so I tend to unplug it and bring it with 
me, so I can use it with different computers.  Obviously, when the 
dongle isn't present, there's no point running the "bluetooth" service, 
and when I plug it in, kbluetoothd (from the KDE Bluetooth project) 
detects the dongle pretty much instantly, but then complains that the 
SDP service isn't running.  Is there any way I could add triggers to the 
hotplug service for my dongle that would start 
/etc/rc.d/init.d/bluetooth when it's inserted, and stop it when it's 
removed?

Thanks!
