Keep losing /dev/cu.usbmodemXXXX on OS X

Galileo usbmodem device keeps randomly disappearing from /dev and I am no longer able to upload my code to Galileo. The only way I've been able to reliably get it back is to reboot my laptop. This is really frustrating. I am using the Intel Arduino IDE with the latest version of OS X. Has anyone seen this issue?

Hello MrPrezident,

How are you powering your board? According to your description it sounds like the board might be having powering issues?

We could determine it, if you have a serial cable, could you try to connect to the board's terminal?

What do you see? Is the board rebooting itself?

Peter.

I'm powering it with a 12V power supply. Good idea about the serial cable. I think I have one. I'll give it a try.

Yes, give it a try and let us know if you notice any strange behavior.
