I patched the camera1394_dev.cpp to simply issue a waring instead of a fatal error and that made the whole thing work. Unfortunately I do not have sufficient experience with other cameras, so I do not know wheter this "fix" would cause problems elsewhere. I don't have enough experience either, really. But, I think your fix is a good idea. That's what I intended to try when I asked if camera1394 was failing for those cameras. I expect issuing the warning and continuing to be a safer change than taking out the reset completely. Since it works for you, please send the patch. I'll try it here for regression testing, then commit the fix. If you don't have a patch handy, just let me know. It's easy to reproduce, I just prefer to start with something known to work.
