All of a sudden, after a couple of failed tries serial usb is working now using JLINK interface firmware and mbed binary. My example code is:

    #include "mbed.h"              

   Serial pc(USBTX, USBRX);

   int main() {
     pc.printf("Echoes back to the screen anything you type\n");
       while(1) {
       pc.putc(pc.getc());
     }
   }

Thanks!!

The UART over USB on the JLink version is most-definitely fully functional on the DK. I don't know what pc.printf() does, perhaps it doesn't use it correctly. If you set the UART up correctly with the correct pins, initialize it etc and run a suitable terminal session on the other end, it works.
