I got an Adafruit gemma a few days ago and have been toying around with the idea of using it to power some neopixels (which I'm going to sew onto an Iron Man toy).
I was able to compile and send the script I wrote to the gemma using my desktop iMac at home, but am currently around a friend's house, with a Macbook Pro, and it isn't working
Basically, when I'm using the iMac, I connect it to the USB port the red light on the gemma pulses. When it stops pulsing, I'm able to press the bootloader button, and it pulses again. Trying to do the same via my Macbook Pro but this doesn't happen when connecting it to the Macbook Pro, and it doesn't work. No pulsing light after plugging it in, and no pulsing light after pressing the button.
