Has anyone thought about a way to do this, probably with a userland daemon=
=20
(perhaps multiple, one per user or something) to act upon device insertion?

=46or instance, I have a "car GPS / mp3 player" and that means two devices:

	Garmin StreetPilot 2610
	External keypad to control xmms :)

However, the procedure to hot-plug these devices is currently:

	int fd =3D -1;
	while (fd < 0) {
		fd =3D open();
			if (fd < 0)
				sleep(1);
	}

or for usbhidaction, a shell script to restart it when it dies.

This really isn't optimal.  :)

I was thinking of using kqueue, but the kevent structure doesn't have any w=
ay=20
to extend the structure to include additional fields beyond the int64_t dat=
a=20
field.  I suppose I could stuff a pointer in there, but that seems like a=20
hack.  I could add an external data pointer and length, but now the caller=
=20
would need to clean up the event's additional data.

Do I write yet another method to do this, or should I hack on kqueue to stu=
ff=20
this in?
