Error with sample sketch - USB Shield 2 xbox controller

I installed this library:

My intention is to use the XBOX Wireless controller with a usb shield on arduino.
Opened the sample sketch in Arduino software, and button "Verify". The result is this:

In file included from /home/user/sketchbook/libraries/USBShield2/xboxEnums.h:21:0,

const int8_t index = ButtonIndex(b);

Is this error a bug in the new library version, or is my error? How can i solve this?
Thanks for attention.

You seem to have a problem with button index , but you need to show us your code , using code tags

I solved the problem using the last version of the library on GitHub - felis/USB_Host_Shield_2.0: Revision 2.0 of USB Host Library for Arduino.
Other developer merged a recent update.

Thanks.
