If Linux detects media insertion instantly or Windows detects media insertion instantly (which I can confirm), there is some signal available, so looking at the Linux driver should provide a clue as to what to look for and that can be added to the FreeBSD umass driver. It would be a very desirable addition, but I am not volunteering as I currently don't use such devices. (And, no one would like the terrible code I would write, anyway.) -- R.
