usb host shield from linksprite?

linksprite usb host shield has anyone had experance with this shield or sny usb host shield im using the librarie from Gethub the only thing displayed in serial monitor is Osc did not start. i briefly had it saying Bluetooth library started but no recent luck with anything else and ive tried bluetooth and usb connections

I recently bought one of these and had same problem..you have to use external power on the ardunio. Also I found an incorrect resistor value on the board. This board had issues with providing good 5 volts to usb..

Working now using boot keyboard example
