Thanks very much Josh. Yes the device is found :

Loading firmware image: /usr/share/uhd/images/usrp1_fw.ihx... done
-- UHD Device 0
Device Address:
    type: usrp1
    serial: 4c745353

Just to be crystal clear, A UHD implementation of a GNURadio-Companion file is 
the same as GNURadio i.e. source is USRP not UHD for USRP1?

Also, when I populate with the DBSRX2 in addition to LFRX, can I run both? I 
saw a post from August saying something about only 1 i/o path at the moment.

Hopefully, I will be smarter in 2011.

      Kind Regards,
