Alan, looks the "suspend failed because a port is resuming" messages" is nothing to do with the autosuspend delay, and increase the delay doesn't make the messages disappear[1]. The message is produced because port change event is missed while host is sending ports resuming signal. I have post one patch which may remove the message, see link[2].
