Yeah. Although parallel ports aren't officially hot-pluggable, it does happen
quite often that you want to go out and discover devices at some time after
boot. You can already do that with modules, by unloading and reloading, but
that isn't completely satisfactory.
I think maybe the thing to do is provide some hook to have parport behave as
if a port had been removed and then re-introduced - that is, just do
"detach_driver_chain(port); parport_announce_port(port);" or something vaguely
equivalent. That will cause all the IEEE 1284 discovery to happen anew, and
drivers using the "new style" API will get an opportunity to go hunting for
their own devices. I don't think PARIDE actually falls into this category
right now, but converting it would be a worthwhile project anyway.
Since parallel ports don't have any hardware to detect when devices are
inserted or removed, this can't be triggered manually. But even if the user
has to do it by hand, it would probably be better than the current situation.
