4. USB-to-Serial Drivers

Before you connect your Orangutan USB programmer to your computer, you must

install

the driver

[http://www.pololu.com/docs/0J7/]

for the programmer’s CP2102 USB-to-UART

bridge. Once you have successfully installed your this driver, you should see the green USB
status LED near the mini-B connector lit whenever it is connected to your computer.
