The stock firmware on the USRP2 (which was released prior to the
invention of UHD), doesn't
  support UHD.  You'll have to burn the appropriate image into the USRP2
for it to support UHD.
  The UHD "wire protocol" has undergone several revisions in the last
year as well, so it's good to
  have your USRP2 firmware match the host-side software.  Further, the
stock USRP2 firmware
  doesn't have an IP stack at all--it used so-called "raw ethernet"
frames for communications, so it's
  not able to respond to pings, which use the ICMP ECHO (part of IP)
protocol.

You'll find that the build-gnuradio script will have installed firmware
images in:

/usr/local/share/uhd/images

And you can use /usr/local/share/uhd/utils/usrp2_card_burner_gui.py to
place new firmware and FPGA
  images onto your USRP2 SD card.
