Error uploading firmata to arduino

[elie-g]

I followed the steps shown here and I got the following error.

Maybe I did something wrong, but in this case there should be a proper error message telling me what I did wrong.

[elie-g]

I specified the path to the arduino (/dev/ttyACM0) and it worked. Though, the steps I was following said Gort would use this device by default.

Anyway, like I said, there should be a proper error message telling me I have to specify the device instead of an error stacktrace.
