USB shield host library errors on arduino uno

Hi I just got the and was wondering how i could read the serial data from the usb port on the shield, I tried using the USB HOST Shield 2.0 library that can be found in the add library part f the arduino ide as well as the library linked in the product descriptio under the same name, however in both cases it faialed to verify the library part and has=d issues wit every part of the library

does anyone know a fix for this or a work around

if it uses one of the 4 serial interface on the Mega, isn't it Serial1, Serial2 or Serial3?

its using arduino uno, i also tried some of the libraries mentioned in youtube videos but all seem to give errors
