Hi the board seems to be recognised, it shows up in /dev as ttyUSB0. Dmesg shows:
ftdi_sio 5-2:1.0: FTDI USB Serial Device converter detected ftdi_sio: Detected FT232RL usb 5-2: FTDI USB Serial Device converter now attached to ttyUSB0 usb 5-2: New USB device found, idVendor=0403, idProduct=6001 usb 5-2: New USB device strings: Mfr=1, Product=2, SerialNumber=3 usb 5-2: Product: FT232R USB UART usb 5-2: Manufacturer: FTDI usb 5-2: SerialNumber: A40018qs
The problem is the tools-> serial port oprion in the menu is greyed out and when i try to upload to the arduino i get the ERROR:
processing.app.SerialException: Serial port 'COM1' not found. Did you select the right one from the Tools > Serial Port menu?
I have changed the serial port option in the arduino/lib/preferences.txt file to /dev/ttyUSB0 but i still get the COM1 error suggesting the preferences isnt being recognised.
