Exactly.
I must say I have not tried if there is some timeout on this, that it
will disappear after a time. But even then you would not be able to sync
between the timeouts.

it seems the hal_device_added is always called at least twice. One time
it already exits here
if (!(bus = libhal_device_get_property_string (hal_ctx, udi, "info.bus",
NULL))) {
		return;
	}
So you can't do anything with that I think.

The second time it exits here
if (strcmp (bus, "usb_device") != 0 ) {
	libhal_free_string (bus);
	return;
}
and it seems bus it set to "usb".  My best guess is that when you get an
adding where bus = usb, you might be able to ask hal if there is already
a palm "usb_device" available, and if so, use it. But I have no idea how
to do that :-)
