MacOS will do that :-) (and, sadly, so will 'doze)

I looked into hotplug a little, unintentionally, when I was trying to get my
Visor to sync on USB to Linux. My problem was related to using the uhci
module instead of usb-uhci so that might be one place to look. However, from
what I remember of the hotplug stuff you need to register a device class
with the hotplug subsystem so that when it sees a "Canon A20" appearing it
knows what to do. This is what you do in 'doze or on MacOS when you install
a driver for a USB device. Of course you install the driver software but
you also in some way register the device class/type to be recognised when
its plugged in - hence the admonitions on USB installation instructions to
install the software BEFORE plugging in the device.  Ferret round in the
hotplug directories - sorry not to be more specific but I can't remember
where I read this - I think it was in a script in the hotplug directories.
