Arduino

• solving "moving usb port"

http://blenderartists.org/forum/archive/index.php/t-150503.html

And just one remark more. I fixed the problem with port numbers by adding a file 97-arduino.rules in /etc/udev/rules.d/ and adding following rule:
kernel=="ttyUSB*", SYSFS{idVendor}=="0403", SYSFS{idProduct}=="6001", SYMLINK="Arduino"
So now I can always trust that Arduino is in /dev/Arduino
