I tried to convert a creative VF0070 usb camera to 1394 camera by inserting a (4 pin 1394 male to usb male out) converter into my laptop's 1394 port and connected the camera's usb male connector to a (usb female-female) in order to connect to the 1394 connector. but labview NI-IMAQ vi's are not able to detect the camera. can anybody tell me how to use a USB camera as 1394 camera since my usb vis are not working properly with the camera.
