Connect schield holes to GND

Hi, I have tried to search a lot but without finding a good sollution. Maybe I used the wrong keys to search for.

My problem is as follows. When I use for example the USB-B-PTH component from the Sparkfun Eagle library I have the mounting holes of the component. Somehow I am unable to connect these to GND is there a sollution for it.

Any help is verry mutch apreciated

With the PCB software I use I’d simply assign the Gnd net to the holes. You must be able to do something similar with Eagle. According to the USB spec. the shield shouldn’t be grounded at the device end, anyway.
