permission denied to pins when non-root

I’m trying to do this:

I’m running ubuntu on my beaglebone black with nodejs 0.8.x

I can’t figure out how to get it running without running as root. It seems like there is some sort of permissions problem with my user because the project runs fine under root. I added myself to the user group dialout but it didn’t make a difference. My question is, what do I need to do to give my user permission to the pin states. The crash looks like this:

return, stringToFlags(flags), mode);
Error: EACCES, permission denied ‘/sys/class/leds/beaglebone:green:usr0/trigger’

Thanks in advance.

Has this been resolved? I have been searching up and down for a solution. How can anyone get anything working on ubuntu distro with this clear problem?
