Right, I'm using USB Host Shield with Arduino Uno. I'm very new with Arduino - please forgive me in advance for silly questions.
The shield is connected and red power LED is ON.

When I plug in a USB device, e.g. IPOD or USB memory stick nothing happens. I connected a 9 V external power supply - still nothing happens when USB devices are connected.

I installed the USB Host Shield 2.0 library and tried to compile example USB_desc.pde. I get error compiling with the following,

I am attaching my ~/.arduino/preferences.txt What else can I do?
