First I'd throw some thought on if there is some similar interfacing
structure already out in the world. If other people already use this
device for my viewpoint it is desirable to use the same api on the
userland side.
With some more copy paste you'll be able to install Plug/Unplug
Notifications (simply retain the matching dictionary from a previous
finddevice and reuse it for notifications). Then you are able to do the
whole init procedure of a device in its notification.
Either send an apple event from this notification (and init) to your
main app event loop or use some other approach that does not poll from
the main app loop.
btw I did it with some other polling. Though I have to trigger reads on
usb with an runloop timer and if a new device is found it is placed in a
chained list of devices which also is worked down by this kicker timer.
For me it is safe to also modify this chained list from other places.
Don't know if this works for you.
