Walter,
Thanks. Sorry if this is elementary. So, I download both files on the XO, and
then run the rules script?

Just a lttle explanation for less familiar folks:Gnu/Linux has various
sub-system to connect the outside world to the world inside your computer. One
of those systems is involved with USB devices('udev' -- user devices). When you
plug-in a USB device, the kernel tries to find a kernel module to talk to
it(with UDEV rules) and if it succeeds, it makes a device entry in the 'dev'
directory (/dev/ttyUSB0 or something). If this happens, your device is
recognized and other Gnu/Linux programs can 'see' it, if not, they will keep
looking and fail to find it and nothing will happen or an error message will be
displayed. There are multiple components to make TurtleArt work with the
sensors/boards/etc. One is to load the plugin, two is to setup the 'udev'
rules', three is to have a kernel modules that works and four is to plug in the
device. So pluging-in the device, loading the plugin, are two steps but two
more are needed. If the kernel modules is present, then
all you need to do is add the UDEV rules with the script and that should make
everything work.ARDUINO->USB port->kernel module->udev rule->usb device
node->turtle art plugin->turtle artor something like that.hope that helps.-K_______________________________________________
