I'd like to add another data point to this thread with the new Videre STOC camera I recently acquired but I'm having difficulty getting off the ground. The camera works fine under Windows using the SVS software, so then I tried it under Ubuntu 10.04 (kernel 2.6.32-25) on the same machine (dual boot) and therefore using the same hardware. Running coriander I get the following error: "Warning: could not find a Digital Camera on the bus". So I already suspect something wrong with Firewire under my Ubuntu setup. But I press on anyway. When first trying to run smallv I got the following error: "error while loading shared libraries: libraw1394.so.8: cannot open shared object file: No such file or directory" I have set LD_LIBRARY_PATH correctly according to the Videre instructions so I did: sudo ln -s libraw1394.so.11.0.1 libraw1394.so.8 which is the version on my system and now smallv comes up fine. However, it does not see the camera on my Firewire port. In the Debug window I see that no IEEE 1394 cards are found: SVS Debugging Window Pixel depth: 24 [dSystem] 0 card(s) found, 0 node(s) [dSystem] No IEEE1394 card found SVS version 4.4f -- DCS Digital Stereo Interface MMX presence: 7 0 devices found: I made sure I am a member of both the disk and video groups and I did a chmod 777 on dev/video1394/* so that ls -l dev/video1394/* gives: crwxrwxrwx+ 1 root video 171, 16 2011-02-12 07:59 0 crwxrwxrwx+ 1 root video 171, 17 2011-02-12 07:59 The output from lsmod includes: raw1394 22271 0 video1394 13050 0 ohci1394 26950 1 video1394 ieee1394 81181 3 raw1394,video1394,ohci1394 One last thing: I have registration keys for the SVS software, one for Windows and one for Linux. The Windows key was necessary for installation but I don't see any reference to how to install the Linux key so I don't know if that could be the problem. No doubt I am missing some key step to setting up Firewire under Ubuntu but I am stumped.
