At a minimum, you will need to call pick_tx_bitrate and pick_rx_bitrate providing proper rates for the ADC and DAC. They default to the values appropriate for the USRP1. However, it looks like you'll need a USRP2 version since they encode the acceptable ranges for interpolation and decimation which are different between the USRP1 and USRP2.
