[USRP-users] Problems recognizing daughterboard on USRP1

You have a very old RFX board.  You'll need to modify it to become an 
RFX2400_MIMO_B.  Follow the instructions here:

http://gnuradio.org/redmine/wiki/1/USRPClockingNotes?version=8

The relevant section is:

To modify these boards for coherent applications if you have USRP rev 4 
boards:

     * Recent boards don't need these mods, only early RFX-boards
     * Move R64 to R84, Move R142 to R153
           o This disables the daughterboard clocks
     * Move R35 to R36, Move R117 to R115
           o This connects the boards to the motherboard clock
           o These are all 0-ohm, so if you lose one, just short across 
the appropriate pads
     * Plug the board into side A of your USRP and execute one of the 
following commands to reprogram the dboard EEPROM:
           o usrp/host/apps/burn-db-eeprom -A -t rfx400_mimo_b --force
           o usrp/host/apps/burn-db-eeprom -A -t rfx900_mimo_b --force
           o usrp/host/apps/burn-db-eeprom -A -t rfx2400_mimo_b --force
