Hi everyone!

I just downloaded swissranger_camera to try our SR4000 with ROS.

I previously installed libmesasr as required. However when I try to run
swissranger_camera the node wont even connect to the camera:

"blazz@blazz-ros:~$ rosrun swissranger_camera swissranger_camera

camera:
[SR::open]: Failed to open device!"

I noticed that swissranger_camera works for libmesasr API >=1.0, and at the
mesa website I found the following statement:

"The API interface has changed from driver version 1.0.8.xxx to 1.0.10.xxx
Existing applications based on the 1.0.8.xxx driver must be adapted to the
new interface."

Could it be that the version currently available at the mesa website no
longer works with swissranger_camera? Or am I just missing something out?

Thanks for the help,
