[ros-users] Mesa SwissRanger SR4000 and swissranger_camera

[David Dröschel]

Hi Gonçalo,

have you checked your permissions?

We add this to our udev rules:

SUBSYSTEM=="usb", ACTION=="add", SYSFS{idVendor}=="1ad2", 
SYSFS{idProduct}=="0075", MODE="660", GROUP="plugdev"

I think the package doesn't compile with the wrong libmesasr version.
