Hi all, Sorry for being late. I didn't know this maillist before. As for the project, the firewire subsystem doesn't publish a device node for every attached 1394 device. So the method used by usb_webcam which monitor the device node in /dev/bus/usb/ doesn't work for firewire dv. Is there another way to tell the media server to rescan the flavor? Regards, JiSheng
