I believe that 1394 scanners will maintain state through bus resets, as 1394 bus resets are not as disruptive as scsi bus resets (all that's really required 1394-wise is for the initiator to "reconnect" to the target). They should only lose state if actually unplugged from the bus itself. But... this is the behavior I would "expect" (have not verified this)... ;-) Cheers, --James _______________________________________________ Linux-hotplug-devel mailing list http://linux-hotplug.sourceforge.net Linux-hotplug-devel@lists.sourceforge.net http://lists.sourceforge.net/lists/listinfo/linux-hotplug-devel
