No, it's just what it says. "Interface" is the first element of what might
be an array of entries. You get to the other elements like this:

PUSBD_INTERFACE_INFORMATION* Interfaces =
&(urb->UrbSelectConfiguration.Interface);

This is why you use UsbBuildSelectConfigurationRequest to build the URB: so
the structure gets allocated large enough.
