FTDI USB Drivers for win xp, 7
The FTDI USB Drivers are installed with Arduino IDE package, but have at least in my case to be installed manually by browsing for the "arduino.inf" for the two devices under windows.

- Click on the Start Menu, and open up the Control Panel.
- While in the Control Panel, navigate to System and Security. Next, click on System. Once the System window is up, open the Device Manager.
- Look under Ports (COM & LPT). You should see an open port named "Arduino UNO (COMxx)". If there is no COM & LPT section, look under "Other Devices" for "Unknown Device".
- Right click on the "Arduino UNO (COmxx)" port and choose the "Update Driver Software" option.
- Next, choose the "Browse my computer for Driver software" option.
- Finally, navigate to and select the driver file named "arduino.inf", located in the "Drivers" folder of the Arduino Software download (not the "FTDI USB Drivers" sub-directory). If you are using an old version of the IDE (1.0.3 or older), choose the Uno driver file named "Arduino UNO.inf"
- Windows will finish up the driver installation from there.

Check if the USB cable you use is for data or just for power. Some cables may omit the data lines. The included cable in our kit should have the data line.
If it doesn't work, you may search "FTDI Serial Adapter FT232RL FT232 TTL 5V" on eBay or other online store. If it works, I will reimburse the cost.
