Nanode, USB FTDI, OSX10.7
Contents
Nanode
The nanode is an Arduino clone with a built in Ethernet controller.
The annoying error:
0 0 AppleUSBCDC: start - initDevice failed
It's taken me a long time (not that long, just some debugging across systems) to get it to work on OSX10.7, you program it through a UART port (or as Nanode call it.. FTDI) the UART Adaptor that comes with Nanode has a silicon labs CP2102 interface chip. Nanode recommend installing the FTDIdriver that comes with arduino form ftdichip.com, however it's a Silicon labs chip which was why everyone had problems with the initial connection and gave up.
Driver OSX/WINDOWS - Linux doesn't need any
Get them from here: http://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx bad news to OSX users for some silly reason you need to reboot your computer once installed.
You should see this in dmesg after reboot..

..Great!
cp2102 pinout
Nanode -> cp2102 solder on a 1pin to the DTR line
RTS* -> DTR* TXD -> rx RXD -> tx +5V -> 5V 0V -> gnd
Note the rx and tx wire pairs are swapped and not straight through like used for the BoArduino. A good idea is to use the common colour convention of green or black for ground and red for the 5V. another approach is simply to keep each wire in order (as much as possible), so it is easier to see how they are connected.
Differences and Preparation
First, if you test blink! on the Nanode it wont work, pin 13 is connected to the network adaptor, while pin 6 is now connected to the onboard LED.. so just change pin 13 to 6.. done
tested
https://github.com/jcw/ethercard - failed to work.
