For interest, I changed the 1394 pci adapter card to a newer Belkin. hwinfo reports the older adapter as well as this one; but "hwinfo --camera" still gives nothing. Can anyone get camera information from hwinfo? Perhaps hwinfo is simply unable to detect a 1394 camera.

What should exist? Is it persistent? Or does it come into existence only when Coriander is running the V4L service? > ... and your user account should be member of the necessary > group(s) of course. Which groups? I don't recognize any group as specific to V4L. Should there be a *v4l* group? Thanks, ... Peter E. -- Telephone 1 360 639 0202.
