The tessel node module seems to have installed properly, but when I try 'tessel update' I get an error.
When I plug the USB in, in addition to the power LED, i see red, orange and blue LEDs (for ~30s and then they go out. I've tried power cycle + config button, as well as the reset + config button... but neither seems to have any effect.
$ tessel version
$ node -v
$ sudo tessel update
TESSEL? ERR! No devices found.
I've tried three Tessel boards, with three different USB cords on mac, linux and windows... all with the same result. Any further troubleshooting steps I can try?
