No - the platform will either send an event for the port or for an individual device. It'll never simultaneously send one for both the port and a device. Semantically the one from the port is a "check all children" request and the one from the device a "check this individual device", but I believe these are both equivalent in the current hotswap implementation. -- Matthew Garrett | [EMAIL PROTECTED] - To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
