No devices available via serial

I'm trying to get to a "Hello World" with my new Photon. I've been able to flash new software onto the device through Build. I'm running on an Ubuntu 14.04 machine with the Photon plugged in to USB. I can't seem to bring up a terminal to the device though. So I installed Particle CLI, and typed "particle serial list" which gives back this result:

Error listing serial ports: { [Error: ENOENT, scandir '/dev/serial/by-id'] errno: -2, code: 'ENOENT', path: '/dev/serial/by-id' }
No devices available via serial

I have to imagine this this a common problem with a known solution, but I haven't found anything through google-fu. Can anyone offer a clue?

Ubuntu lists the USB serial differently and we have seen this issue before. This thread might be useful: USB Connection Problems. Ubuntu 14.04 [Solved: use sudo]

Ah there it is /dev/ttyACM0 thanks!
