I wrote a prg which polls for a given USB device and executes a script
when the device is plugged in or out.  The problem is that this prg can
cause a kernel panic under 2.0.2 - I think there must be a race condition
which causes the panic if the USB devices are polled at the "wrong" time
(exactly at the moment when a new device is being attached, probably).

I was going to use this prg and script to mount my digicam, move all pics
to hd and then umount the disk - but I don't like the kernel panic that
much :(
