[ros-users] Bumblebee2 v1.0 release

[Jürgen Sturm]

Hi Soonhac,

thanks for the driver, howeve rI'm having the same problems as Abe:
the driver hangs on my computer after calling dc1394_capture_dequeue.
With coriander, I can view the video from one of the cameras (so
firewire etc is working properly).

After I launch the bumblebee node (and terminate it again with
killall, because ctrl-c/z does not work), coriander also is unable to
grab images from the camera, probably because of the unclean shutdown.

Did anybody find a solution (or the reason) for this problem?

Thanks
Juergen
