Hi,

I'm playing with a brand new Fio v3 and I can't seem to get any code to upload. I've been doing the proper double-tap reset, but I keep getting a jssc.SerialPortException saying "Port Busy". The port (/dev/ttyACM0) is the correct one and I have installed all of the proper board definitions.

Setup:

• Arduino 1.6.2
• Fedora 21
• Fio v3
• USB (i.e. not XBee)

The error message is:

processing.app.debug.RunnerException

The port (/dev/ttyACM0) shows up in the /dev directory when the Fio is connected (it is the port I typically see for ATMega32U4-based boards), but it does not show up in the Arduino IDE.

Any ideas?
