No undue haste please. Let's do it right the first time.
We do agree that device addition must be processed fully, before
device removal is processed, don't we ?
Then we have the problem of device node reuse. It means that
a user space script for addition of a new device must not be run before all
removal handlers are completed.
At least I see no alternative.
But I am not sure that synchronous operation is free of deadlocks.
What happens if a CardBus USB Controller with devices attached is plugged in ?
Regards
Oliver
