BPv4 EXVUSB in Schematic?

Is EXVUSB connected to anything in the current BPv4 schematic ( http://dangerousprototypes.com/docs/ima ... v4-cct.png )?
I can't see that net anywhere else; should it be connected via some switch (physical or transistor) to VUSB?

EXVUSB is connected between the USB connector and the ferrite bead.

I still can't find the connection to EXVUSB... Is the schematic I linked the newest version posted?

The current available PCBs and the Seeed dev-version are v4a in the SVN. EXVUSB is from the pin labeled VUSB to the red tube looking part. If you click info on that connection it says EXVUSB. Here is a screenshot. It is poorly done because the footprint says VUSB there too, but it is no thte name of the trace.

Ahh, gotcha. Just wanted to make sure it wasn't a missing connection!

Thanks!
